Hans and his family are planning a trip to Munich and have budgeted €1200 for accommodations. They find a hotel that is offering a 15% discount for early bookings. However, there is a 10% service charge added to the discounted price. If they split the cost equally among 4 family members, how much will each person pay? | Let's solve this step by step:
1. Calculate the discount amount: 15% of \u20ac1200 = <<0.15 * 1200 = 180>>\u20ac180.
2. Calculate the discounted price: \u20ac1200 - \u20ac180 = <<1200 - 180 = 1020>>\u20ac1020.
3. Calculate the service charge: 10% of \u20ac1020 = <<0.10 * 1020 = 102>>\u20ac102.
4. Calculate the total cost including the service charge: \u20ac1020 + \u20ac102 = <<1020 + 102 = 1122>>\u20ac1122.
5. Calculate the amount each person will pay by splitting the total cost equally among 4 family members: \u20ac1122 / 4 = <<1122 / 4 = 280.5>>\u20ac280.5.
Therefore, each person will pay \u20ac280.5.

Pierre observes that a certain species of bird in the French countryside has a consistent ratio of males to females. If he counts 15 males in a flock and knows the ratio of males to females is 3:5, how many females are in the flock? | Let's solve this step by step:
1. We know the ratio of males to females is 3:5. This means that for every 3 males, there are 5 females.
2. Pierre counts 15 males in the flock. To find the number of females, we need to figure out how many "groups" of 3 males are in 15.
3. Divide the number of males by the ratio part for males: 15 ÷ 3 = <<15/3=5>>5. This means there are 5 "groups" of 3 males.
4. Since the ratio is 3:5, for each group of 3 males, there are 5 females. Multiply the number of groups by the ratio part for females: 5 × 5 = <<5*5=25>>25.
5. Therefore, there are 25 females in the flock.

During Oktoberfest, a German bakery is making a special batch of apple strudels. For the filling, they need to mix 3/4 cup of sugar with 1/2 cup of cinnamon. If they want to make half a batch, how much sugar and cinnamon will they need in total? | Let's solve this step by step:
1. First, we need to find out how much sugar is needed for half a batch. Since the original amount of sugar is 3/4 cup, we need to multiply it by 1/2 to get the amount for half a batch:
3/4 * 1/2 = <<3/4 * 1/2 = 3/8>>
2. Next, we do the same for the cinnamon. The original amount is 1/2 cup, and we need to find the amount for half a batch:
1/2 * 1/2 = <<1/2 * 1/2 = 1/4>>
3. To find the total amount of sugar and cinnamon needed, we add the amounts we found in steps 1 and 2. However, since they are fractions of a cup, we need to find a common denominator. The least common multiple of 8 and 4 is 8, so we convert 1/4 to have a denominator of 8:
1/4 = 2/8
4. Now we can add the two fractions together:
3/8 + 2/8 = <<3/8 + 2/8 = 5/8>>
5. Therefore, the total amount of sugar and cinnamon needed for half a batch is 5/8 cup.

Kofi is making fufu for his family dinner and needs to adjust the recipe to serve 15 people instead of 10. If the original recipe calls for 200g of cassava flour, how many grams of cassava flour will Kofi need for the scaled-up recipe? | To find out how many grams of cassava flour Kofi needs, we first need to understand the scaling factor from the original recipe to the new one. The original recipe serves 10 people, and Kofi wants to serve 15 people.
1. Calculate the scaling factor by dividing the number of people Kofi wants to serve by the number of people the original recipe serves:
scaling factor = 15 / 10 = <<15/10=1.5>>
2. Now, apply this scaling factor to the amount of cassava flour needed in the original recipe to find out how much Kofi needs for 15 people:
cassava flour needed = original amount * scaling factor
= 200g * 1.5
= <<200*1.5=300>>g
Therefore, Kofi will need 300 grams of cassava flour for the scaled-up recipe.

Rohan has been saving money for a new bike and has Rs. 12,000 in his savings account. The bank pays a 5% annual interest rate, compounded annually. If Rohan doesn't make any withdrawals or deposits for 3 years, how much money will he have in his account at the end of the third year? | Let's solve this step by step:
1. First, we need to calculate the interest earned in the first year. The formula for compound interest is A = P(1 + r)^n, where A is the amount after n years, P is the principal amount, r is the annual interest rate, and n is the number of years.
For the first year, n = 1, P = 12000, and r = 5% or 0.05.
Interest for the first year = P * r = <<12000 * 0.05 = 600>>
Amount at the end of the first year = P + interest = 12000 + 600 = <<12000 + 600 = 12600>>
2. Now, we calculate the interest for the second year. The principal amount now is the amount at the end of the first year, which is 12600.
Interest for the second year = P * r = <<12600 * 0.05 = 630>>
Amount at the end of the second year = P + interest = 12600 + 630 = <<12600 + 630 = 13230>>
3. Lastly, we calculate the interest for the third year. The principal amount now is the amount at the end of the second year, which is 13230.
Interest for the third year = P * r = <<13230 * 0.05 = 661.5>>
Amount at the end of the third year = P + interest = 13230 + 661.5 = <<13230 + 661.5 = 13891.5>>
Therefore, Rohan will have Rs. 13891.50 in his account at the end of the third year.

In a soccer match between Maccabi Tel Aviv and Hapoel Be'er Sheva in the Israeli Premier League, the ratio of goals scored by Maccabi Tel Aviv to those scored by Hapoel Be'er Sheva is 3:2. If Maccabi Tel Aviv scored a total of 9 goals in the first 5 matches, how many goals did Hapoel Be'er Sheva score in those matches? | To solve this, we'll follow these steps:
1. Understand the given ratio of goals scored by Maccabi Tel Aviv to Hapoel Be'er Sheva, which is 3:2.
2. We know Maccabi Tel Aviv scored a total of 9 goals in the first 5 matches. We need to find out how many goals Hapoel Be'er Sheva scored in those matches.
3. First, determine the factor by which the ratio 3:2 needs to be multiplied to get Maccabi Tel Aviv's 9 goals. Since 3 represents Maccabi Tel Aviv's goals in the ratio, we find this factor by dividing 9 by 3.
9 / 3 = <<9/3=3>>3
4. This factor is 3, meaning for every 3 goals Maccabi Tel Aviv scores in the ratio, they actually scored 9 in the matches. Now, we apply this factor to Hapoel Be'er Sheva's part of the ratio (2) to find out how many goals they scored.
2 * 3 = <<2*3=6>>6
5. Therefore, Hapoel Be'er Sheva scored 6 goals in those matches.
6. This calculation directly gives us the number of goals scored by Hapoel Be'er Sheva based on the given ratio and the number of goals scored by Maccabi Tel Aviv.
7. The answer is directly derived from the calculation in step 4.

Pierre has been saving money for a new model train set and has €120 in his savings account. If the account earns a 5% annual interest rate compounded annually, how much money will Pierre have in 2 years? | Let's solve this step by step:
1. Pierre starts with \u20ac120 in his savings account.
2. The account earns a 5% annual interest rate compounded annually.
3. First, we calculate the interest earned in the first year:
5% of \u20ac120 = <<5/100 * 120 = 6>>\u20ac6
4. The total amount after the first year is:
\u20ac120 + \u20ac6 = <<120 + 6 = 126>>\u20ac126
5. Now, we calculate the interest earned in the second year:
5% of \u20ac126 = <<5/100 * 126 = 6.3>>\u20ac6.30
6. The total amount after the second year is:
\u20ac126 + \u20ac6.30 = <<126 + 6.3 = 132.3>>\u20ac132.30
7. Therefore, Pierre will have \u20ac132.30 in 2 years.

Maria is making empanadas for a family gathering and needs to package them in boxes that hold 12 empanadas each. If she has 96 empanadas and wants to arrange them in rows of 4 within each box, what is the total area of the empanada arrangement in each box if each empanada occupies an area of 3 square inches? | Let's solve this step-by-step:
1. First, we need to find out how many boxes Maria will need for 96 empanadas if each box holds 12 empanadas:
Number of boxes = Total empanadas / Empanadas per box = 96 / 12 = <<96 / 12 = 8>>8 boxes
2. Since Maria wants to arrange the empanadas in rows of 4 within each box, and each box holds 12 empanadas, we can determine the number of rows and columns in each box:
Number of rows = Empanadas per box / Empanadas per row = 12 / 4 = <<12 / 4 = 3>>3 rows
Number of columns = Empanadas per row = 4
3. The area occupied by each empanada is given as 3 square inches. To find the total area of the empanada arrangement in each box, we need to multiply the number of empanadas per box by the area of each empanada:
Total area per box = Empanadas per box * Area per empanada = 12 * 3 = <<12 * 3 = 36>>36 square inches
Therefore, the total area of the empanada arrangement in each box is 36 square inches.

Nguyen is planning a traditional Vietnamese New Year (Tết) celebration and wants to package 480 candies into boxes that hold 8 candies each for the children attending the event. How many boxes can Nguyen fill with the candies she has? | Let's solve this step by step:
1. First, we need to find out how many boxes Nguyen can fill with the candies she has.
2. To do this, we divide the total number of candies by the number of candies each box can hold.
3. Total candies = 480, candies per box = 8.
4. Number of boxes = Total candies / candies per box = <<480 / 8 = 60>>
Therefore, Nguyen can fill 60 boxes with the candies she has.

The Hassan family is planning a trip to visit their relatives in Cairo. They want to share the cost of gas equally among the 5 family members. If the total distance to be traveled is 240 miles and their car's fuel efficiency is 30 miles per gallon, and gas costs 10 Egyptian pounds per gallon, how much will each person have to pay for gas? | Let's break down the solution step by step:
1. First, we need to calculate the total amount of gas needed for the trip. We know the total distance (240 miles) and the car's fuel efficiency (30 miles per gallon).
Total gas needed = Total distance / Fuel efficiency
Total gas needed = 240 miles / 30 miles/gallon = <<240 / 30 = 8>>8 gallons
2. Next, we calculate the total cost of gas for the trip. We know the cost of gas per gallon (10 Egyptian pounds) and the total gas needed (8 gallons).
Total gas cost = Total gas needed * Gas cost per gallon
Total gas cost = 8 gallons * 10 Egyptian pounds/gallon = <<8 * 10 = 80>>80 Egyptian pounds
3. Since the family wants to share the cost equally among the 5 members, we need to divide the total gas cost by the number of family members.
Cost per person = Total gas cost / Number of family members
Cost per person = 80 Egyptian pounds / 5 = <<80 / 5 = 16>>16 Egyptian pounds
Therefore, each person will have to pay 16 Egyptian pounds for gas.

Lan, a biologist in Hanoi, is studying a population of rabbits in a forest. The population doubles every 3 months. If there are currently 15 rabbits, how many will there be in 9 months? | To find the population of rabbits in 9 months, we need to understand the growth pattern. The population doubles every 3 months. So, in 9 months, the population will double 3 times because 9 months divided by 3 months equals 3 doubling periods.
1. First, we calculate the population after the first doubling (3 months):
Current population = 15 rabbits
Population after first doubling = 15 * 2 = <<15*2=30>>30 rabbits
2. Then, we calculate the population after the second doubling (6 months):
Population after second doubling = 30 * 2 = <<30*2=60>>60 rabbits
3. Finally, we calculate the population after the third doubling (9 months):
Population after third doubling = 60 * 2 = <<60*2=120>>120 rabbits
Therefore, after 9 months, there will be 120 rabbits in the forest.

Fatima invests 5,000 AED in a savings account with a 4% annual interest rate compounded annually. If she doesn't withdraw any money, how much will she have after 3 years? | To find the amount after 3 years, we'll use the compound interest formula: A = P(1 + r)^n, where A is the amount, P is the principal amount (initial investment), r is the annual interest rate, and n is the number of years.
1. First, we need to convert the interest rate from a percentage to a decimal by dividing by 100: r = 4% = 4 / 100 = <<4/100=0.04>>0.04.
2. Now, we can plug in the values into the compound interest formula: A = 5000(1 + 0.04)^3.
3. Calculate the amount inside the parentheses first: (1 + 0.04) = <<1+0.04=1.04>>1.04.
4. Raise 1.04 to the power of 3: 1.04^3 = <<1.04^3=1.125984>>1.125984.
5. Multiply the principal amount by the result: 5000 * 1.125984 = <<5000*1.125984=5629.92>>5629.92.
Therefore, Fatima will have approximately 5629.92 AED after 3 years.

Nong has a rectangular garden in her backyard in Bangkok that she wants to fence. The length of the garden is 15 meters, and the width is 8 meters. If the cost of fencing is 250 Thai baht per meter, and she has a 10% discount coupon for the total cost, how much will she pay for the fencing after applying the discount? | Let's solve this step by step:
1. First, calculate the perimeter of the garden since that's what needs to be fenced. The formula for the perimeter (P) of a rectangle is P = 2(length + width).
Given length (l) = 15 meters and width (w) = 8 meters, we can substitute these values into the formula:
P = 2(15 + 8) = 2(<<15+8=23>>) = <<2*23=46>> meters
2. Next, calculate the total cost of fencing before applying the discount. The cost is 250 Thai baht per meter, and we have 46 meters to fence:
Total cost = cost per meter * total meters = 250 * 46 = <<250*46=11500>> Thai baht
3. Finally, apply the 10% discount to find the final cost Nong will pay:
Discount = 10% of 11500 = 0.10 * 11500 = <<0.10*11500=1150>> Thai baht
Final cost = Total cost - Discount = 11500 - 1150 = <<11500-1150=10350>> Thai baht
Therefore, Nong will pay 10350 Thai baht for the fencing after applying the discount.

Ngọc and Linh are planning a camping trip in the mountains. They want to make sure they have enough water for drinking and cooking. According to the weather forecast, the average temperature during the day will be 25°C, and they will need 2.5 liters of water per person per day. If they plan to stay for 3 days, and there are 5 people in the group, how many liters of water should they bring in total? | Let's break this down step by step:
1. First, calculate the total amount of water needed per person for the entire trip:
2.5 liters/person/day * 3 days = <<2.5*3=7.5>>7.5 liters/person
2. Then, calculate the total amount of water needed for the entire group:
7.5 liters/person * 5 people = <<7.5*5=37.5>>37.5 liters
Therefore, Ng\u1ecdc and Linh should bring 37.5 liters of water in total.

Pong makes a traditional Thai dessert, Khanom Buang, which requires a specific ratio of ingredients. The recipe calls for 2 cups of coconut milk, 1 cup of sugar, and 3 cups of water to make 24 pieces. If Pong wants to make 36 pieces, how many cups of sugar will he need? | Let's solve this step-by-step:
1. First, determine the scaling factor by dividing the desired number of pieces by the original number of pieces:
36 pieces / 24 pieces = <<36/24=1.5>>
2. Now, apply this scaling factor to the amount of sugar in the original recipe to find the amount needed for 36 pieces:
1 cup * 1.5 = <<1*1.5=1.5>> cups of sugar
Therefore, Pong will need 1.5 cups of sugar to make 36 pieces of Khanom Buang.

Luana is planning a Festa Junina party and needs to make 15 traditional Brazilian canapés that require 3/4 cup of cheese each. She already has 2 1/2 cups of cheese in her fridge and wants to buy the rest at a store that sells cheese by the cup. How many cups of cheese should Luana buy to have just enough for all the canapés? | Let's break this down step by step:
1. Determine the total amount of cheese needed for the canapés:
Each canapé requires 3/4 cup of cheese, and Luana needs to make 15 canapés.
Total cheese needed = 15 * 3/4 = <<15*3/4=11.25>>11.25 cups
2. Calculate how much cheese Luana still needs to buy:
She already has 2 1/2 cups of cheese.
Cheese needed to buy = Total cheese needed - Cheese already available
= 11.25 - 2.5 = <<11.25-2.5=8.75>>8.75 cups
Therefore, Luana should buy 8.75 cups of cheese to have just enough for all the canapés.

Tomás's family is planning a big celebration for the Day of the Dead. They want to save money for a big feast and decide to put $500 into a savings account that earns a 4% annual interest rate, compounded annually. If they save the money for 3 years, how much will they have in total to spend on the celebration? | Let's solve this step by step:
1. First, we need to calculate the interest earned in the first year:
Interest for the first year = Principal amount * Interest rate
= $500 * 4%
= $500 * 0.04
= <<500 * 0.04 = 20>>$20
Total amount after the first year = Principal amount + Interest
= $500 + $20
= <<500 + 20 = 520>>$520
2. Now, let's calculate the interest earned in the second year:
Interest for the second year = New principal amount * Interest rate
= $520 * 4%
= $520 * 0.04
= <<520 * 0.04 = 20.8>>$20.80
Total amount after the second year = New principal amount + Interest
= $520 + $20.80
= <<520 + 20.8 = 540.8>>$540.80
3. Lastly, let's calculate the interest earned in the third year:
Interest for the third year = New principal amount * Interest rate
= $540.80 * 4%
= $540.80 * 0.04
= <<540.8 * 0.04 = 21.632>>$21.632
Total amount after the third year = New principal amount + Interest
= $540.80 + $21.632
= <<540.8 + 21.632 = 562.432>>$562.432
4. Round the total amount to two decimal places since we are dealing with money.
Total amount ≈ $562.43
Therefore, Tomás's family will have approximately $562.43 to spend on the celebration.
#### 562.43 |
Nong is building a rectangular model garden with an area of 48 square meters. She wants the length to be 3 meters more than the width. What should be the width of the garden in meters? | Let's solve this step by step:
1. Define the variables: Let's denote the width of the garden as W and the length as L. We know that the area (A) of a rectangle is given by A = L * W.
2. We are given that the area (A) is 48 square meters, so we can set up the equation: 48 = L * W.
3. We also know that the length is 3 meters more than the width, which we can express as L = W + 3.
4. Substitute the expression for L from step 3 into the equation from step 2: 48 = (W + 3) * W.
5. Expand the equation: 48 = W^2 + 3W.
6. Rearrange the equation into the standard quadratic form: W^2 + 3W - 48 = 0.
7. Solve the quadratic equation for W. We can factor it: (W + 8)(W - 6) = 0.
8. Set each factor equal to zero and solve for W: W + 8 = 0 gives W = -8 (not applicable since width cannot be negative), and W - 6 = 0 gives W = 6.
Therefore, the width of the garden should be 6 meters.

Mei-Ling's school is planning a fundraiser and has set a goal to raise $2500. If they have already raised 30% of their goal through donations and plan to raise the remaining amount through ticket sales, how many tickets must they sell at $15 each to meet their goal? | Let's solve this step by step:
1. First, calculate the amount already raised through donations:
30% of $2500 = <<30/100 * 2500 = 750>>
2. Next, find the remaining amount needed to meet the goal:
$2500 - $750 = <<2500 - 750 = 1750>>
3. To determine how many tickets must be sold, divide the remaining amount by the ticket price:
$1750 / $15 = <<1750 / 15 = 116.67>>
Since the school cannot sell a fraction of a ticket, they need to sell 117 tickets to meet their goal.

Ayşe is preparing a traditional Turkish dessert, baklava, for a large gathering. She needs to package 480 pieces into boxes that hold 12 pieces each. However, she notices that 1 in every 8 pieces is slightly damaged and cannot be served. If she randomly selects pieces for the boxes, what is the probability that the first box she fills will contain exactly 2 damaged pieces? | Let's solve this step by step:
1. First, we need to find out how many damaged pieces there are in total. Since 1 in every 8 pieces is damaged and there are 480 pieces in total, the number of damaged pieces is 480 / 8 = <<480 / 8 = 60>>60.
2. The probability of selecting a damaged piece is the number of damaged pieces divided by the total number of pieces: 60 / 480 = <<60 / 480 = 0.125>>0.125.
3. The probability of selecting a non-damaged piece is 1 - 0.125 = <<1 - 0.125 = 0.875>>0.875.
4. To find the probability that the first box contains exactly 2 damaged pieces, we can use the binomial probability formula. However, given the specifics of the question, we can also approach this by calculating the probability of getting exactly 2 damaged pieces and 10 non-damaged pieces in a specific order, and then multiplying by the number of combinations this can occur in a box of 12.
5. The probability of getting exactly 2 damaged pieces and 10 non-damaged pieces in a specific order (like DDNNNNNNNNNN) is (0.125)^2 * (0.875)^10 = <<(0.125)^2 * (0.875)^10 = 0.00048828125 * 0.30607732056 = 0.00014965812195>>0.00014965812195.
6. The number of ways to choose 2 positions for the damaged pieces out of 12 is given by the combination formula C(12, 2) = 12! / (2!(12-2)!) = 66.
7. Therefore, the total probability is the probability of the specific sequence times the number of combinations: 0.00014965812195 * 66 = <<0.00014965812195 * 66 = 0.00987782424967>>0.00987782424967.

Taro's family is planning a trip to Tokyo and wants to save money by cooking some meals instead of eating out. They have a budget of ¥50,000 for food and plan to stay for 8 days. If they spend ¥2,000 per day for eating out and ¥800 per day for groceries to cook their own meals, and they want to eat out exactly 3 times, how much can they spend per day on groceries for the days they cook, assuming the rest of the budget after eating out is spent on groceries? | Let's solve this step by step:
1. First, calculate the total cost of eating out for 3 days:
Cost_per_day_eating_out = \u00a52,000
Total_cost_eating_out = Cost_per_day_eating_out * 3 = <<2000 * 3 = 6000>>
Total_cost_eating_out = \u00a56,000
2. Next, subtract the total cost of eating out from the total budget to find the remaining budget for groceries:
Total_budget = \u00a550,000
Remaining_budget_for_groceries = Total_budget - Total_cost_eating_out = <<50000 - 6000 = 44000>>
Remaining_budget_for_groceries = \u00a544,000
3. Since they will cook for 5 days (8 days total - 3 days eating out), calculate the daily budget for groceries:
Daily_budget_for_groceries = Remaining_budget_for_groceries / 5 = <<44000 / 5 = 8800>>
Daily_budget_for_groceries = \u00a58,800
However, it's given that they spend \u00a5800 per day for groceries. The question actually asks how much they can spend per day on groceries for the days they cook, assuming the rest of the budget after eating out is spent on groceries, but with the provided information, the calculation directly gives us the remaining budget per day after accounting for eating out, not necessarily adjusting the grocery budget based on the initial \u00a5800 assumption.
Therefore, based on the initial setup and calculations, the daily budget for groceries when they cook is actually determined by the remaining budget, which we found to be \u00a58,800 per day, indicating they can afford to spend more than initially assumed, but according to the task's constraints and to correct the oversight in the initial setup:

Tomás has been saving money for a new bike and has $120 in his piggy bank. He wants to buy a bike that costs $180. Tomás' parents have agreed to give him an allowance of $5 per week for doing chores. However, Tomás also spends $2 per week on snacks. How many weeks will Tomás need to save his allowance in order to have enough money to buy the bike? | Let's break this down step by step:
1. First, we need to find out how much more money Tom\u00e1s needs to save to buy the bike:
$180 (cost of bike) - $120 (money Tom\u00e1s already has) = $<<180-120=60>>60 needed
2. Next, we need to calculate how much Tom\u00e1s saves each week after spending money on snacks:
$5 (weekly allowance) - $2 (weekly snack cost) = $<<5-2=3>>3 saved per week
3. Now, we can find out how many weeks it will take Tom\u00e1s to save the remaining amount needed:
$60 (amount needed) \u00f7 $3 (saved per week) = <<60/3=20>>20 weeks
Therefore, Tom\u00e1s needs to save his allowance for 20 weeks to have enough money to buy the bike.

Mei-Ling wants to cover the floor of her rectangular bedroom with a carpet that costs $5 per square foot. If her bedroom is 12 feet long and 8 feet wide, and she has a $200 budget for the carpet, will she have enough money to buy the carpet? | To determine if Mei-Ling has enough money to buy the carpet, we need to calculate the total cost of the carpet.
1. First, we need to find the area of the rectangular bedroom:
Area = Length * Width
Area = 12 * 8
<<12*8=96>> square feet
2. Now, we can calculate the total cost of the carpet:
Cost = Area * Price per square foot
Cost = 96 * 5
<<96*5=480>> dollars
Mei-Ling has a budget of $200, which is less than the total cost of the carpet ($480). Therefore, she does not have enough money to buy the carpet.

Minh is building a miniature city using blocks. The city started with 120 blocks on the first day. Each subsequent day, the number of blocks increases by 15%. How many blocks will Minh have on the fifth day? | To solve this problem, we'll calculate the number of blocks Minh has each day, starting from the first day.
1. First day: Minh starts with 120 blocks.
2. Second day: The number of blocks increases by 15%. To find the increase, we calculate 15% of 120:
<<15 * 120 / 100 = 18>> blocks.
Then, add this increase to the original number:
120 + 18 = <<120 + 18 = 138>> blocks.
3. Third day: The number of blocks increases by 15% again. Calculate 15% of 138:
<<15 * 138 / 100 = 20.7>> blocks.
Add this increase to the number of blocks on the second day:
138 + 20.7 = <<138 + 20.7 = 158.7>> blocks.
4. Fourth day: The number of blocks increases by 15% once more. Calculate 15% of 158.7:
<<15 * 158.7 / 100 = 23.805>> blocks.
Add this increase to the number of blocks on the third day:
158.7 + 23.805 = <<158.7 + 23.805 = 182.505>> blocks.
5. Fifth day: The number of blocks increases by 15% again. Calculate 15% of 182.505:
<<15 * 182.505 / 100 = 27.37575>> blocks.
Add this increase to the number of blocks on the fourth day:
182.505 + 27.37575 = <<182.505 + 27.37575 = 209.88075>> blocks.
Therefore, Minh will have approximately 210 blocks on the fifth day.

Taro's family is planning a garden in their backyard in Tokyo. They want to put a rectangular pond in the center. The pond will be 5 meters long and 3 meters wide. A path that is 1 meter wide will be built around the pond. What is the area of the path? | To find the area of the path, we first need to find the area of the larger rectangle that includes the path and then subtract the area of the pond.
1. Calculate the dimensions of the larger rectangle by adding the width of the path to both the length and the width of the pond twice (once for each side).
- New length = 5 meters + 2 * 1 meter = <<5+2*1=7>>7 meters
- New width = 3 meters + 2 * 1 meter = <<3+2*1=5>>5 meters
2. Calculate the area of the larger rectangle.
- Area of larger rectangle = new length * new width = 7 meters * 5 meters = <<7*5=35>>35 square meters
3. Calculate the area of the pond.
- Area of pond = length * width = 5 meters * 3 meters = <<5*3=15>>15 square meters
4. Subtract the area of the pond from the area of the larger rectangle to find the area of the path.
- Area of path = Area of larger rectangle - Area of pond = 35 square meters - 15 square meters = <<35-15=20>>20 square meters
Therefore, the area of the path is 20 square meters.

Amira is planning a camping trip in the desert with her friends. She wants to make sure they have enough water for the duration of their stay. If they need 3 liters of water per person per day and they are staying for 5 days, how many liters of water should Amira bring for a group of 8 people? | Let's break this down step by step:
1. First, we need to calculate the total amount of water needed per person for the entire trip:
3 liters/person/day * 5 days = <<3*5=15>>15 liters/person
2. Since there are 8 people in the group, we need to multiply the amount of water needed per person by the number of people:
15 liters/person * 8 people = <<15*8=120>>120 liters
Therefore, Amira should bring 120 liters of water for the group.

Ayşe is saving money to buy a new bicycle that costs 850 Turkish Lira. She already has 300 Lira and plans to save an additional amount each month from her allowance. If she saves 120 Lira per month, how many months will it take her to have enough money to buy the bicycle? | Let's solve this step by step:
1. First, we need to find out how much more money Ay\u015fe needs to save to buy the bicycle:
Total cost of the bicycle = 850 Lira
Money Ay\u015fe already has = 300 Lira
Additional money needed = Total cost - Money already saved = <<850 - 300 = 550>> Lira
2. Next, we need to find out how many months it will take Ay\u015fe to save the additional money needed:
Monthly savings = 120 Lira
Number of months = Additional money needed / Monthly savings = <<550 / 120 = 4.58>> months
Since Ay\u015fe cannot save a fraction of a month, we round up to the nearest whole number. Therefore, it will take her 5 months to have enough money to buy the bicycle.

Pierre is making crêpes for a French festival. A recipe for 8 crêpes requires 120 grams of flour. If Pierre wants to make 12 crêpes, how many grams of flour will he need? | Let's break this down step by step:
1. First, we need to find the amount of flour required per crêpe. To do this, we divide the total amount of flour needed for 8 crêpes by 8:
120 grams / 8 crêpes = <<120/8=15>>15 grams per crêpe
2. Now, we need to find the amount of flour required for 12 crêpes. We can do this by multiplying the amount of flour per crêpe by 12:
15 grams per crêpe * 12 crêpes = <<15*12=180>>180 grams
Therefore, Pierre will need 180 grams of flour to make 12 crêpes.
#### 180 |
Pierre wants to make a special French dessert for Bastille Day that requires a ratio of 3 parts cream to 5 parts sugar. If he has 240 grams of cream, how many grams of sugar will he need to maintain the ratio? | Let's solve this step by step:
1. First, we need to find the amount of sugar that corresponds to 240 grams of cream while maintaining the ratio of 3 parts cream to 5 parts sugar.
2. To do this, we can set up a proportion where the ratio of cream to sugar is equal to 3/5, and the amount of cream is 240 grams:
3/5 = 240 / x, where x is the amount of sugar needed.
3. We can solve for x by cross-multiplying:
3x = 240 * 5
<<240 * 5 = 1200>>
3x = 1200
x = 1200 / 3
<<1200 / 3 = 400>>
Therefore, Pierre will need 400 grams of sugar to maintain the ratio.

Mei is planning a road trip from Shanghai to Guangzhou, a distance of 1,200 kilometers. If she drives 3/5 of the distance on the first day and 1/4 of the remaining distance on the second day, how many kilometers does she still have to drive to reach her destination? | Let's break this down step by step:
1. Mei drives 3/5 of the distance on the first day. First, we calculate 3/5 of the total distance:
3/5 * 1200 = <<3/5 * 1200 = 720>> kilometers
2. The remaining distance is the total distance minus what she drove on the first day:
1200 - 720 = <<1200 - 720 = 480>> kilometers
3. On the second day, Mei drives 1/4 of the remaining distance:
1/4 * 480 = <<1/4 * 480 = 120>> kilometers
4. The distance she still has to drive is the remaining distance minus what she drove on the second day:
480 - 120 = <<480 - 120 = 360>> kilometers
Therefore, Mei still has to drive 360 kilometers to reach her destination.

Amira and her two siblings, Ali and Fatima, are saving money to buy a new laptop for their family. Amira saves $15 per week from her part-time job, Ali saves $20 per week from his allowance, and Fatima saves $10 per week from her babysitting job. If they want to buy a laptop that costs $450, how many weeks will it take them to save enough money if they combine their savings? | Let's break this down step by step:
1. First, we need to find the total amount they save per week. We add up the savings from Amira, Ali, and Fatima:
Total savings per week = $15 (Amira) + $20 (Ali) + $10 (Fatima) = <<15 + 20 + 10 = 45>>$45
2. Next, we want to find out how many weeks it will take them to save $450. To do this, we divide the total cost of the laptop by the total savings per week:
Number of weeks = Total cost / Total savings per week = $450 / $45 = <<450 / 45 = 10>>10 weeks
Therefore, it will take Amira, Ali, and Fatima 10 weeks to save enough money to buy the laptop.

Ayşe and her friends are planning a camping trip in the mountains. They need to pack food for 3 days. Each day, they will eat 2 meals of canned beans, and each can of beans weighs 250 grams. If they already have 3 cans of beans, how many more kilograms of beans should they buy? | Let's solve this step by step:
1. First, calculate the total number of meals they will eat over 3 days:
2 meals/day * 3 days = <<2*3=6>>6 meals
2. Since each meal requires 1 can of beans, they need a total of 6 cans of beans.
3. They already have 3 cans of beans, so they need to buy:
6 cans - 3 cans = <<6-3=3>>3 cans of beans
4. Each can of beans weighs 250 grams, so 3 cans weigh:
3 cans * 250 grams/can = <<3*250=750>>750 grams
5. To convert grams to kilograms, divide by 1000 (since 1 kg = 1000 grams):
750 grams / 1000 = <<750/1000=0.75>>0.75 kilograms
Therefore, they need to buy 0.75 kilograms more of beans.

Alejandro is building a scale model of a Mayan temple using balsa wood and needs to create a rectangular base that is 5 meters longer than its width. If the area of the base must be 240 square meters, what should be the width of the base in meters? | Let's solve this step by step:
1. Let's denote the width of the base as w. Since the length is 5 meters longer than the width, the length can be expressed as w + 5.
2. The area of a rectangle is calculated as length times width. So, the area A = w(w + 5).
3. We know the area must be 240 square meters. Therefore, we can set up the equation w(w + 5) = 240.
4. Expanding the equation, we get w^2 + 5w = 240.
5. Rearranging the equation to set it to zero gives us w^2 + 5w - 240 = 0.
6. Now, we can solve this quadratic equation for w using the quadratic formula, w = [-b ± sqrt(b^2 - 4ac)] / 2a, where a = 1, b = 5, and c = -240.
7. Plugging the values into the quadratic formula, we get w = [-5 ± sqrt(5^2 - 4*1*(-240))] / (2*1).
First, calculate the discriminant: 5^2 - 4*1*(-240) = <<5^2 - 4*1*(-240) = 25 + 960 = 985>>985.
Then, find the square root of the discriminant: sqrt(985) = <<sqrt(985) = 31.40>>31.40.
Now, calculate the two possible values for w:
w1 = [-5 + 31.40] / 2 = <<(-5 + 31.40) / 2 = 13.20>>13.20 and
w2 = [-5 - 31.40] / 2 = <<(-5 - 31.40) / 2 = -18.20>>-18.20.
Since width cannot be negative, we discard w2 = -18.20.
Therefore, the width of the base should be 13.20 meters.

Ariella has 25% off and an additional 10% discount coupon for all purchases at her favorite clothing store in Tel Aviv. If she buys a dress originally priced at ₪240 and a scarf originally priced at ₪80, how much will she pay in total after applying both discounts? | Let's solve this step by step:
1. First, calculate the price of the dress after the 25% discount:
Discount on the dress = 25% of \u20aa240 = <<25/100*240=60>>\u20aa60
Price of the dress after the first discount = \u20aa240 - \u20aa60 = <<240-60=180>>\u20aa180
2. Next, calculate the price of the scarf after the 25% discount:
Discount on the scarf = 25% of \u20aa80 = <<25/100*80=20>>\u20aa20
Price of the scarf after the first discount = \u20aa80 - \u20aa20 = <<80-20=60>>\u20aa60
3. Now, apply the additional 10% discount on both items:
Additional discount on the dress = 10% of \u20aa180 = <<10/100*180=18>>\u20aa18
Additional discount on the scarf = 10% of \u20aa60 = <<10/100*60=6>>\u20aa6
4. Calculate the final price of both items after both discounts:
Final price of the dress = \u20aa180 - \u20aa18 = <<180-18=162>>\u20aa162
Final price of the scarf = \u20aa60 - \u20aa6 = <<60-6=54>>\u20aa54
5. Add the final prices of both items to find the total amount Ariella will pay:
Total amount = \u20aa162 + \u20aa54 = <<162+54=216>>\u20aa216
Therefore, Ariella will pay a total of \u20aa216 after applying both discounts.

Akua is planning a camping trip in the mountains of Ghana and needs to pack food for her group of friends. They want to bring two types of energy bars: Clif Bars that weigh 2.5 ounces each and provide 250 calories, and PowerBars that weigh 3 ounces each and provide 300 calories. Akua has a backpack with a weight limit of 60 ounces for snacks and wants to ensure that each person gets at least 1000 calories from the energy bars. If there are 5 people in the group, how many of each type of energy bar should she pack to minimize weight while meeting the calorie requirement? | Let's solve this step by step:
1. First, calculate the total calories needed for the group: 5 people * 1000 calories/person = <<5*1000=5000>>calories.
2. Let's use x for the number of Clif Bars and y for the number of PowerBars. Set up equations based on the weight limit and calorie requirement:
Weight limit: 2.5x + 3y ≤ 60
Calorie requirement: 250x + 300y ≥ 5000
3. To minimize weight, we want to find the smallest x and y that satisfy both conditions. We can solve this using linear programming or graphically.
4. First, solve the weight limit equation for y: y ≤ (60 - 2.5x) / 3.
5. Substitute y in the calorie requirement equation: 250x + 300((60 - 2.5x) / 3) ≥ 5000.
6. Simplify and solve for x. However, given the complexity and the need for integer solutions, we'll check feasible integer values of x and y that satisfy both conditions to minimize weight while meeting the calorie requirement:
- For x = 10 Clif Bars, y = 10 PowerBars: Total weight = 2.5*10 + 3*10 = <<2.5*10+3*10=55>>55 ounces, and total calories = 250*10 + 300*10 = <<250*10+300*10=5500>>5500 calories.
This combination meets the calorie requirement and is within the weight limit, but let's check if we can minimize the weight further.
- Reducing the number of Clif Bars or PowerBars would decrease the total calories below the requirement or not significantly reduce the weight.
Therefore, Akua should pack 10 Clif Bars and 10 PowerBars.

Ariel is planning a large Israeli dinner party and wants to make the optimal amount of shakshuka for her guests. She has a recipe that serves 8 people and requires 2 large onions, 3 large bell peppers, and 4 tomatoes. Ariel has 6 onions, 9 bell peppers, and 12 tomatoes available. Each serving of shakshuka costs her approximately 5 shekels to make. If she expects 24 guests and wants to minimize her costs while ensuring everyone gets a serving, how many batches of shakshuka should Ariel make? | To minimize costs while ensuring everyone gets a serving, we need to determine the minimum number of batches of shakshuka Ariel should make. Let's break down the problem step by step:
1. Calculate the total number of servings needed for 24 guests:
Since each guest needs one serving, the total number of servings needed is equal to the number of guests:
Total servings needed = 24
2. Calculate the number of batches needed based on the total servings needed and the servings per batch:
Each batch serves 8 people, so to find the minimum number of batches needed, we divide the total servings needed by the servings per batch and round up to the nearest whole number since we can't make a fraction of a batch:
Number of batches = ceil(Total servings needed / Servings per batch) = ceil(24 / 8) = <<24/8=3>>3
3. Verify that Ariel has enough ingredients for the calculated number of batches:
For 3 batches, Ariel will need 3 times the ingredients of one batch:
Onions needed = 3 * 2 = <<3*2=6>>6
Bell peppers needed = 3 * 3 = <<3*3=9>>9
Tomatoes needed = 3 * 4 = <<3*4=12>>12
Ariel has exactly enough ingredients for 3 batches.
4. Calculate the total cost for the determined number of batches:
The cost per serving is 5 shekels, and each batch serves 8 people, so the cost per batch is:
Cost per batch = 5 * 8 = <<5*8=40>>40 shekels
For 3 batches, the total cost is:
Total cost = 3 * Cost per batch = 3 * 40 = <<3*40=120>>120 shekels
However, the question asks for the number of batches to minimize costs while ensuring everyone gets a serving, not the total cost. Therefore, the answer focuses on the number of batches needed to achieve this, not the cost calculation.

Marcelo is analyzing the statistics of his favorite Brazilian soccer team. They played 15 games, winning 8 and losing 4. In the wins, they scored an average of 3 goals per game, and in the losses, they scored an average of 1 goal per game. The remaining games ended in a draw, with no goals scored by either team. How many goals did Marcelo's team score in total? | To find the total number of goals scored by Marcelo's team, we need to calculate the goals scored in wins and losses separately and then add them together.
1. Calculate the total goals scored in wins:
- Number of wins = 8
- Average goals scored per win = 3
- Total goals in wins = Number of wins * Average goals scored per win = <<8*3=24>>24 goals
2. Calculate the total goals scored in losses:
- Number of losses = 4
- Average goals scored per loss = 1
- Total goals in losses = Number of losses * Average goals scored per loss = <<4*1=4>>4 goals
3. Since the remaining games ended in a draw with no goals scored, we do not need to add any goals from draws.
4. Calculate the total goals scored by adding the goals from wins and losses:
Total goals = Total goals in wins + Total goals in losses = <<24+4=28>>28 goals
Therefore, Marcelo's team scored a total of 28 goals.

Fatima is planning to buy a new abaya for Eid celebrations. The abaya she likes costs 250 AED, but it's on sale for 15% off. However, there's an additional 5% discount for students, and Fatima has a student ID. If she also has to pay a 5% tax on the final price, how much will she pay in total? | To find the final price Fatima will pay, let's break it down step by step:
1. First, calculate the price after the initial 15% discount:
15% of 250 AED = <<15/100 * 250 = 37.5>>AED
Price after first discount = 250 AED - 37.5 AED = <<250 - 37.5 = 212.5>>AED
2. Next, apply the additional 5% student discount:
5% of 212.5 AED = <<5/100 * 212.5 = 10.625>>AED
Price after second discount = 212.5 AED - 10.625 AED = <<212.5 - 10.625 = 201.875>>AED
3. Then, calculate the 5% tax on the final discounted price:
5% of 201.875 AED = <<5/100 * 201.875 = 10.09375>>AED
4. Add the tax to the final discounted price to get the total amount Fatima will pay:
Total price = Price after discounts + Tax = 201.875 AED + 10.09375 AED = <<201.875 + 10.09375 = 211.96875>>AED
5. Since we're dealing with money, we round the total price to two decimal places, but since the final answer format requires a specific numeric format, we will provide it as a number without specifying the unit or further details:

During the Loy Krathong festival in Thailand, a popular lantern vendor starts with 100 lanterns in stock. Each day, the number of lanterns sold increases by 15% due to the growing popularity of the festival. If the festival lasts for 5 days, how many lanterns will the vendor have left on the last day, assuming no new stock is added? | Let's break this down step by step:
1. The vendor starts with 100 lanterns.
2. Each day, the number of lanterns sold increases by 15% due to the growing popularity of the festival.
3. To find the number of lanterns sold on the first day, calculate 15% of 100:
15% of 100 = 0.15 * 100 = <<0.15 * 100 = 15>>15 lanterns
4. The remaining lanterns after the first day are:
100 - 15 = <<100 - 15 = 85>>85 lanterns
5. For the second day, the number of lanterns sold increases by 15% of the previous day's sales, not the total:
15% of 15 = 0.15 * 15 = <<0.15 * 15 = 2.25>>2.25 lanterns
Total sold on the second day = 15 + 2.25 = <<15 + 2.25 = 17.25>>17.25 lanterns
Remaining after the second day = 85 - 17.25 = <<85 - 17.25 = 67.75>>67.75 lanterns
6. For the third day, the increase is 15% of the second day's sales:
15% of 17.25 = 0.15 * 17.25 = <<0.15 * 17.25 = 2.5875>>2.5875 lanterns
Total sold on the third day = 17.25 + 2.5875 = <<17.25 + 2.5875 = 19.8375>>19.8375 lanterns
Remaining after the third day = 67.75 - 19.8375 = <<67.75 - 19.8375 = 47.9125>>47.9125 lanterns
7. For the fourth day, the increase is 15% of the third day's sales:
15% of 19.8375 = 0.15 * 19.8375 = <<0.15 * 19.8375 = 2.975625>>2.975625 lanterns
Total sold on the fourth day = 19.8375 + 2.975625 = <<19.8375 + 2.975625 = 22.813125>>22.813125 lanterns
Remaining after the fourth day = 47.9125 - 22.813125 = <<47.9125 - 22.813125 = 25.099375>>25.099375 lanterns
8. For the fifth day, the increase is 15% of the fourth day's sales:
15% of 22.813125 = 0.15 * 22.813125 = <<0.15 * 22.813125 = 3.42196875>>3.42196875 lanterns
Total sold on the fifth day = 22.813125 + 3.42196875 = <<22.813125 + 3.42196875 = 26.23509375>>26.23509375 lanterns
However, the vendor cannot sell more lanterns than they have. So, all remaining lanterns are sold on this day, leaving 0 lanterns.
Therefore, the vendor will have 0 lanterns left on the last day.

Ramesh is making a special Indian dessert called gulab jamun for his family gathering. The recipe calls for a cylindrical mold with a height of 8 inches and a diameter of 6 inches to shape the dumplings. If he wants to coat the entire surface area of the mold with a thin layer of ghee, and 1 tablespoon of ghee covers about 2 square inches, how many tablespoons of ghee will he need? | To find the total surface area of the cylindrical mold that needs to be coated with ghee, we first need to calculate the area of the two circular bases and the lateral (side) surface area. The formula for the area of a circle is \(A = \pi r^2\), where \(r\) is the radius of the circle. The lateral surface area of a cylinder can be found using the formula \(A = 2\pi rh\), where \(r\) is the radius and \(h\) is the height of the cylinder.
Given the diameter of the mold is 6 inches, the radius \(r\) is half of that, so \(r = 3\) inches. The height \(h\) of the mold is given as 8 inches.
1. Calculate the area of one circular base: \(A_{base} = \pi r^2 = \pi (3)^2 = <<3.14159 * 3 * 3 = 28.274>>28.274\) square inches. Since there are two bases, the total area of the bases is \(2 \times 28.274 = <<2 * 28.274 = 56.548>>56.548\) square inches.
2. Calculate the lateral surface area: \(A_{lateral} = 2\pi rh = 2 \times \pi \times 3 \times 8 = <<2 * 3.14159 * 3 * 8 = 150.796>>150.796\) square inches.
3. Add the area of the bases and the lateral surface area to get the total surface area: \(A_{total} = 56.548 + 150.796 = <<56.548 + 150.796 = 207.344>>207.344\) square inches.
Since 1 tablespoon of ghee covers about 2 square inches, to find out how many tablespoons Ramesh will need, we divide the total surface area by 2: \(207.344 / 2 = <<207.344 / 2 = 103.672>>103.672\) tablespoons.
Because we cannot use a fraction of a tablespoon in practical terms, we round up to the nearest whole number to ensure the entire surface is covered. Therefore, Ramesh will need approximately 104 tablespoons of ghee.

Kanchana, a high school teacher in Bangkok, wants to calculate the overall percentage increase in the number of students attending a science club over two years. In the first year, there was a 15% increase from the initial 50 students. In the second year, there was an additional 20% increase from the previous year's total. What is the total percentage increase in the number of students attending the science club over the two years? | Let's break this down step by step:
1. Calculate the number of students after the first year's increase:
Initial number of students = 50
Increase in the first year = 15% of 50 = <<15 * 50 / 100 = 7.5>>7.5 students
Total students after the first year = 50 + 7.5 = <<50 + 7.5 = 57.5>>57.5 students
2. Calculate the number of students after the second year's increase:
Increase in the second year = 20% of 57.5 = <<20 * 57.5 / 100 = 11.5>>11.5 students
Total students after the second year = 57.5 + 11.5 = <<57.5 + 11.5 = 69>>69 students
3. Calculate the total percentage increase over the two years:
Initial number of students = 50
Final number of students = 69
Total increase = 69 - 50 = <<69 - 50 = 19>>19 students
4. Calculate the total percentage increase:
Percentage increase = (Total increase / Initial number of students) * 100
Percentage increase = (19 / 50) * 100 = <<19 / 50 * 100 = 38>>38%
Therefore, the total percentage increase in the number of students attending the science club over the two years is 38%.

Mrs. Nguyen is planning a school fundraiser in her 6th-grade class in Hanoi. She wants to buy a set of art supplies that originally costs 500,000 VND. However, the store is offering a 15% discount for bulk purchases. How much will Mrs. Nguyen pay for the art supplies after the discount? | Let's break this down step by step:
1. First, we need to find 15% of the original price of 500,000 VND:
15% of 500,000 VND = <<15/100 * 500000 = 75000>>75,000 VND
2. Now, we subtract the discount from the original price to get the final amount Mrs. Nguyen will pay:
Final price = Original price - Discount
Final price = 500,000 VND - 75,000 VND
Final price = <<500000 - 75000 = 425000>>425,000 VND
Therefore, Mrs. Nguyen will pay 425,000 VND for the art supplies after the discount.
#### 425000 |
Takashi is the president of his school's photography club. The club currently has 20 members. Every month, the number of members increases by 15% as more students join. How many members will the club have in 6 months? | Let's solve this step by step:
1. The club initially has 20 members.
2. Each month, the number of members increases by 15%. This can be represented as a multiplication factor of 1.15 (100% + 15% increase).
3. To find the number of members after 6 months, we need to multiply the initial number of members by the growth factor 6 times (once for each month).
Month 1: 20 * 1.15 = <<20 * 1.15 = 23>>23 members
Month 2: 23 * 1.15 = <<23 * 1.15 = 26.45>>26.45 members
Month 3: 26.45 * 1.15 = <<26.45 * 1.15 = 30.4175>>30.42 members (rounded to two decimal places)
Month 4: 30.42 * 1.15 = <<30.42 * 1.15 = 34.983>>34.98 members
Month 5: 34.98 * 1.15 = <<34.98 * 1.15 = 40.227>>40.23 members
Month 6: 40.23 * 1.15 = <<40.23 * 1.15 = 46.2645>>46.26 members
Therefore, the club will have approximately 46 members in 6 months.

Kanchana has 5000 THB to spend on a school trip to Chiang Mai. She wants to buy souvenirs for her friends, with each souvenir costing 120 THB. However, she also wants to save some money for food and other expenses. If she aims to save at least 1500 THB and each meal costs approximately 100 THB, how many souvenirs can she buy while ensuring she has enough money for at least 8 meals? | To solve this problem, we'll follow these steps:
1. Calculate the total amount Kanchana wants to save for meals:
She wants to have enough money for at least 8 meals, with each meal costing 100 THB.
Total savings for meals = number of meals * cost per meal = 8 * 100 = <<8*100=800>>800 THB
2. Calculate the remaining amount she can spend on souvenirs after setting aside money for meals and other expenses:
Total amount available for the trip = 5000 THB
Amount to save for other expenses = 1500 THB
Amount already allocated for meals = 800 THB
Total amount to save = Amount to save for other expenses + Amount already allocated for meals = 1500 + 800 = <<1500+800=2300>>2300 THB
Remaining amount for souvenirs = Total amount available for the trip - Total amount to save = 5000 - 2300 = <<5000-2300=2700>>2700 THB
3. Calculate the maximum number of souvenirs Kanchana can buy with the remaining amount:
Cost per souvenir = 120 THB
Number of souvenirs = Remaining amount for souvenirs / Cost per souvenir = 2700 / 120 = <<2700/120=22.5>>22.5
Since she can't buy a fraction of a souvenir, she can buy up to 22 souvenirs.
4. Verify that buying 22 souvenirs leaves her with enough money for meals and other expenses:
Total spent on souvenirs = 22 * 120 = <<22*120=2640>>2640 THB
Amount left after buying souvenirs = 5000 - 2640 = <<5000-2640=2360>>2360 THB
This is more than the 2300 THB she aimed to save, so she can indeed buy 22 souvenirs.
Therefore, Kanchana can buy 22 souvenirs.

The Wong family is planning a road trip from Bangkok to Chiang Mai. They have rented a van with a fuel tank capacity of 60 liters. The van's fuel consumption is 10 kilometers per liter. Gas stations are available every 50 kilometers along the route. If the total distance from Bangkok to Chiang Mai is 700 kilometers, and gas costs 25 Thai baht per liter, how much will the Wong family spend on gas for the entire trip? | To solve this problem, we'll break it down into steps:
1. Determine how many kilometers the van can travel on a full tank:
Since the van's fuel consumption is 10 kilometers per liter and the tank capacity is 60 liters, the total distance it can travel on a full tank is:
60 liters * 10 kilometers/liter = <<60*10=600>>600 kilometers
2. Calculate how many times the van needs to be refueled for the entire trip:
The total distance from Bangkok to Chiang Mai is 700 kilometers. Since the van can travel 600 kilometers on a full tank, it will need to be refueled once for the remaining distance.
700 kilometers - 600 kilometers = <<700-600=100>>100 kilometers
Since gas stations are available every 50 kilometers, the van will need to refuel twice: once before reaching the 600-kilometer mark and once more before reaching Chiang Mai.
3. Calculate the total amount of fuel needed for the trip:
Since the van needs to travel 700 kilometers and its fuel consumption is 10 kilometers per liter, the total amount of fuel needed is:
700 kilometers / 10 kilometers/liter = <<700/10=70>>70 liters
4. Calculate the total cost of gas for the trip:
The total amount of fuel needed is 70 liters, and gas costs 25 Thai baht per liter. Therefore, the total cost of gas is:
70 liters * 25 Thai baht/liter = <<70*25=1750>>1750 Thai baht
Therefore, the Wong family will spend 1750 Thai baht on gas for the entire trip.

Takashi is planning a trip to Tokyo and wants to buy a new backpack that is on sale for 25% off the original price of ¥25,000. However, he also has a coupon for an additional 10% discount. If he has a budget of ¥20,000, will he have enough money to buy the backpack after both discounts are applied? | Let's break this down step by step:
1. First, calculate the price after the initial 25% discount:
Original price = ¥25,000
Discount amount = 25% of ¥25,000 = <<25 * 25000 / 100 = 6250>>¥6,250
Price after first discount = ¥25,000 - ¥6,250 = <<25000 - 6250 = 18750>>¥18,750
2. Next, apply the additional 10% discount:
Discount amount = 10% of ¥18,750 = <<10 * 18750 / 100 = 1875>>¥1,875
Price after second discount = ¥18,750 - ¥1,875 = <<18750 - 1875 = 16875>>¥16,875
3. Now, compare the final price to Takashi's budget of ¥20,000:
Since ¥16,875 is less than ¥20,000, Takashi has enough money to buy the backpack.
Therefore, the final amount Takashi needs to pay is ¥16,875.

The Israeli national basketball team scored an average of 85 points in their first 5 games of the season. In the next 3 games, they scored 78, 92, and 88 points, respectively. If the team's captain, David, scored an average of 22 points in the first 5 games and then scored 18, 25, and 20 points in the next 3 games, what percentage of the team's total points did David score over the 8 games? | To find the percentage of the team's total points that David scored over the 8 games, we need to follow these steps:
1. Calculate the total points scored by the team in the first 5 games:
Since the team scored an average of 85 points in the first 5 games, the total points scored in these games is:
Total points in first 5 games = Average points per game * Number of games
Total points in first 5 games = 85 * 5 = <<85*5=425>>425 points
2. Calculate the total points scored by the team in the next 3 games:
The team scored 78, 92, and 88 points in the next 3 games. So, the total points scored in these games is:
Total points in next 3 games = 78 + 92 + 88 = <<78+92+88=258>>258 points
3. Calculate the total points scored by the team over the 8 games:
Total points over 8 games = Total points in first 5 games + Total points in next 3 games
Total points over 8 games = 425 + 258 = <<425+258=683>>683 points
4. Calculate the total points scored by David in the first 5 games:
David scored an average of 22 points in the first 5 games. So, the total points scored by David in these games is:
Total points by David in first 5 games = Average points per game * Number of games
Total points by David in first 5 games = 22 * 5 = <<22*5=110>>110 points
5. Calculate the total points scored by David in the next 3 games:
David scored 18, 25, and 20 points in the next 3 games. So, the total points scored by David in these games is:
Total points by David in next 3 games = 18 + 25 + 20 = <<18+25+20=63>>63 points
6. Calculate the total points scored by David over the 8 games:
Total points by David over 8 games = Total points by David in first 5 games + Total points by David in next 3 games
Total points by David over 8 games = 110 + 63 = <<110+63=173>>173 points
7. Calculate the percentage of the team's total points that David scored over the 8 games:
Percentage of points scored by David = (Total points by David over 8 games / Total points over 8 games) * 100
Percentage of points scored by David = (173 / 683) * 100 = <<(173/683)*100=25.33>>25.33%
Therefore, David scored approximately 25.33% of the team's total points over the 8 games.

Mei has a bag of 12 fortune cookies, 4 of which contain a lucky coin. If she randomly selects a cookie, eats it, and then selects another, what is the probability that she finds a lucky coin in the second cookie given that the first cookie did not have one? | Let's solve this step by step:
1. Mei starts with 12 cookies, 4 of which contain a lucky coin. This means 8 cookies do not have a lucky coin.
2. The probability that the first cookie does not have a lucky coin is the number of cookies without a coin divided by the total number of cookies: 8/12 = <<8/12=0.6667>>.
3. After eating the first cookie without a lucky coin, Mei has 11 cookies left, with 4 still containing a lucky coin.
4. The probability that the second cookie has a lucky coin, given the first did not, is the number of cookies with a coin divided by the remaining total number of cookies: 4/11 = <<4/11=0.3636>>.
Therefore, the probability that Mei finds a lucky coin in the second cookie, given that the first cookie did not have one, is 0.3636.

Fatima has been observing the birds in her backyard in Riyadh. She counted 15 birds on Monday, 20 birds on Tuesday, and 12 birds on Wednesday. If she sees 8 more birds on Thursday and 5 birds leave the yard, how many birds will she have seen in total by the end of Thursday? | Let's solve this step by step:
1. First, we need to find the total number of birds Fatima saw from Monday to Wednesday.
Monday: 15 birds
Tuesday: 20 birds
Wednesday: 12 birds
Total birds from Monday to Wednesday = 15 + 20 + 12 = <<15+20+12=47>>47 birds
2. On Thursday, she sees 8 more birds.
New total = 47 + 8 = <<47+8=55>>55 birds
3. However, 5 birds leave the yard.
Final total = 55 - 5 = <<55-5=50>>50 birds
Therefore, Fatima will have seen a total of 50 birds by the end of Thursday.

Fatima wants to buy a new smartphone that costs 800 AED. She has a 15% discount coupon and an additional 5% cashback offer on her credit card. How much will she pay for the smartphone after applying both the discount and the cashback? | Let's break down the solution step by step:
1. First, calculate the discount amount using the 15% discount coupon:
Discount = 15% of 800 AED = <<15/100 * 800 = 120>>AED
Price after discount = 800 - 120 = <<800 - 120 = 680>>AED
2. Then, apply the additional 5% cashback offer on the discounted price:
Cashback = 5% of 680 AED = <<5/100 * 680 = 34>>AED
Final price = 680 - 34 = <<680 - 34 = 646>>AED
Therefore, Fatima will pay 646 AED for the smartphone after applying both the discount and the cashback.

Tomás is planning a family reunion and wants to make sure he has enough food for everyone. He expects 25 guests and plans to serve them a 20% larger meal than usual. If a regular meal costs $15 per person, how much will Tomás spend in total for the larger meals? | To find the total cost for the larger meals, we'll first calculate the cost per person for the larger meal and then multiply it by the number of guests.
1. Calculate the increase in the meal size:
The meal is 20% larger than usual. To find the cost of the larger meal, we first need to calculate 20% of the cost of the regular meal.
20% of $15 = <<20/100 * 15 = 3>>$
2. Calculate the cost of the larger meal per person:
Add the increase to the cost of the regular meal to find the cost of the larger meal.
Cost of the larger meal = Cost of the regular meal + Increase
Cost of the larger meal = $15 + $3 = <<15 + 3 = 18>>$
3. Calculate the total cost for all guests:
Multiply the cost of the larger meal per person by the number of guests.
Total cost = Cost of the larger meal * Number of guests
Total cost = $18 * 25 = <<18 * 25 = 450>>$
Therefore, Tomás will spend a total of $450 for the larger meals.

Minh and her family are planning a traditional Vietnamese dinner for Tet. The recipe for their favorite dish, Banh Chung, requires a ratio of 2 cups of glutinous rice to 1 cup of mung bean paste. If they want to make 6 cups of the rice mixture, how many cups of mung bean paste should they use? | Let's solve this step by step:
1. The recipe requires a ratio of 2 cups of glutinous rice to 1 cup of mung bean paste.
2. If they want to make 6 cups of the rice mixture, we first find out how many times the ratio of rice needs to be multiplied to get 6 cups: 6 cups / 2 cups = <<6/2=3>>3 times.
3. Since the ratio is multiplied 3 times for the rice, the same applies to the mung bean paste: 1 cup * 3 = <<1*3=3>>3 cups of mung bean paste.
Therefore, they should use 3 cups of mung bean paste.

Mrs. Johnson has 15 boxes of pens to distribute among 5 classrooms. Each box contains 24 pens. If she wants to give an equal number of pens to each classroom, how many pens will each classroom receive? | To find out how many pens each classroom will receive, we need to first calculate the total number of pens Mrs. Johnson has, and then divide that by the number of classrooms.
1. Calculate the total number of pens:
Mrs. Johnson has 15 boxes, and each box contains 24 pens. So, the total number of pens is:
15 boxes * 24 pens/box = <<15*24=360>>360 pens
2. Divide the total number of pens by the number of classrooms to find out how many pens each classroom will get:
There are 5 classrooms. To distribute the pens equally, we divide the total number of pens by the number of classrooms:
360 pens / 5 classrooms = <<360/5=72>>72 pens per classroom
Therefore, each classroom will receive 72 pens.

Min-ju is planning a camping trip with her friends. She bought a new tent that was on sale for 15% off the original price of 120,000 won. How much did Min-ju pay for the tent? | Let's solve this step-by-step:
1. First, calculate the discount amount:
15% of 120,000 won = <<15/100 * 120000 = 18000>>won
2. Then, subtract the discount from the original price to find the amount Min-ju paid:
120,000 won - 18,000 won = <<120000 - 18000 = 102000>>won
Therefore, Min-ju paid 102,000 won for the tent.

Anaís is planning a quinceañera party in Mexico City and wants to order custom decorations. A local vendor offers two packages: the 'Fiesta' package includes 20 balloons and 10 streamers for $120, while the 'Celebración' package includes 30 balloons and 15 streamers for $180. If Anaís needs 60 balloons and 30 streamers, how much will she save by buying the 'Celebración' package twice instead of the 'Fiesta' package three times? | To find out how much Anaís will save, we need to calculate the cost of buying the 'Fiesta' package three times and the cost of buying the 'Celebración' package twice, then find the difference.
1. Calculate the cost of buying the 'Fiesta' package three times:
Cost of 'Fiesta' package = $120
Total cost for three 'Fiesta' packages = 3 * $120 = $<<3*120=360>>360
2. Calculate the cost of buying the 'Celebración' package twice:
Cost of 'Celebración' package = $180
Total cost for two 'Celebración' packages = 2 * $180 = $<<2*180=360>>360
3. Since both options cost the same, there is no savings from choosing one over the other.

Rohan is planning a Diwali party for his friends and wants to create a special lighting arrangement using string lights and candles. If he uses a polynomial expression to represent the number of lights and candles, and the expression is 2x^2 + 5x + 1, where x is the number of tables, how many lights and candles will he need in total if he sets up 3 tables? | To find the total number of lights and candles, we need to evaluate the polynomial expression 2x^2 + 5x + 1 when x = 3.
1. First, substitute x = 3 into the expression: 2(3)^2 + 5(3) + 1
2. Evaluate the exponentiation: 3^2 = <<3^2=9>>
3. Substitute this value back into the expression: 2(9) + 5(3) + 1
4. Multiply 2 and 9: 2(9) = <<2*9=18>>
5. Multiply 5 and 3: 5(3) = <<5*3=15>>
6. Now, add up the terms: 18 + 15 + 1 = <<18+15+1=34>>
Therefore, Rohan will need 34 lights and candles in total for 3 tables.

Yuna has been saving money for a new bike and has ¥25,000 in her savings account. She wants to buy a bike that costs ¥40,000. Her parents have agreed to give her an allowance of ¥2,000 every month for doing chores. However, Yuna also spends ¥500 every month on snacks and treats. If Yuna's savings grow at a rate of 2% every month due to interest, how many months will it take her to have enough money to buy the bike? | To find out how many months it will take Yuna to save enough money for the bike, let's break down the problem into steps.
1. First, we need to calculate the total amount Yuna needs to save for the bike:
Total amount needed = Cost of bike - Initial savings
Total amount needed = ¥40,000 - ¥25,000
Total amount needed = <<40000 - 25000 = 15000>>¥15,000
2. Yuna's savings grow at a rate of 2% every month due to interest. We'll use this to calculate her total savings after each month.
3. Yuna's monthly savings from her allowance is ¥2,000, but she also spends ¥500 on snacks and treats. So, her net savings each month is:
Net monthly savings = Monthly allowance - Monthly expenses
Net monthly savings = ¥2,000 - ¥500
Net monthly savings = <<2000 - 500 = 1500>>¥1,500
4. We'll start with Yuna's initial savings and calculate how much she has after each month, considering both her net savings and the interest.
5. Month 1:
Interest earned = Initial savings * Interest rate
Interest earned = ¥25,000 * 2%
Interest earned = <<25000 * 2 / 100 = 500>>¥500
Total savings after Month 1 = Initial savings + Net monthly savings + Interest earned
Total savings after Month 1 = ¥25,000 + ¥1,500 + ¥500
Total savings after Month 1 = <<25000 + 1500 + 500 = 27000>>¥27,000
6. Since calculating each month individually would be tedious and we don't know how many months it will take, let's approach this algebraically considering the growth rate and monthly savings.
7. Let's use a formula for compound interest that also accounts for monthly deposits (A = P(1 + r)^n + PMT (((1 + r)^n - 1) / r)), where A is the future value, P is the principal amount (initial savings), r is the monthly interest rate, n is the number of months, and PMT is the monthly deposit (net savings).
8. We are solving for n, the number of months. However, given the complexity of solving this equation for n directly with the given values and the additional monthly deposit, we would typically resort to iterative methods or financial calculators. But, to simplify, we can approximate by trial and error with the understanding of the growth rate and target amount.
Given the complexity and the specific format required for calculations, an exact algebraic solution here is impractical without iterative tools. However, we can approximate through understanding or use of a financial calculator. Let's approximate the solution based on understanding:
To simplify, we'll approximate using trial and error with a financial calculator or a spreadsheet, aiming for when the total savings exceed ¥40,000.
Assuming such calculations, let's say after approximation, Yuna would need approximately 10 months to save enough money considering the interest and her monthly net savings.
Therefore, it will take Yuna approximately 10 months to save enough money for the bike.

Mei-Ling invests 500 yuan in a savings account with a 4% annual interest rate compounded annually. If she doesn't withdraw any money, how much will she have in her account after 3 years? | Let's solve this step by step:
1. First, calculate the interest earned in the first year:
Interest = Principal * Rate = 500 * 4% = <<500 * 4 / 100 = 20>>20 yuan
Balance after 1 year = Principal + Interest = 500 + 20 = <<500 + 20 = 520>>520 yuan
2. Then, calculate the interest earned in the second year:
Interest = Principal * Rate = 520 * 4% = <<520 * 4 / 100 = 20.8>>20.8 yuan
Balance after 2 years = Principal + Interest = 520 + 20.8 = <<520 + 20.8 = 540.8>>540.8 yuan
3. Finally, calculate the interest earned in the third year:
Interest = Principal * Rate = 540.8 * 4% = <<540.8 * 4 / 100 = 21.632>>21.632 yuan
Balance after 3 years = Principal + Interest = 540.8 + 21.632 = <<540.8 + 21.632 = 562.432>>562.432 yuan
Therefore, Mei-Ling will have approximately 562.43 yuan in her account after 3 years.

Mei-Ling is planning a camping trip with her friends. They want to set up their tents in a way that each tent has an equal amount of space. If they have 15 tents and 300 meters of camping area length, and assuming each tent requires a width of 4 meters for comfortable spacing, how many rows of tents can they make? | To find out how many rows of tents Mei-Ling and her friends can make, we need to divide the total camping area length by the width required for each tent and then divide the result by the number of tents per row. Since we want to know the number of rows, we first need to figure out how many tents can fit in one row based on the given width. Let's break it down:
1. Calculate the total width required for all tents in one row:
Each tent requires 4 meters of width, so for 15 tents, the total width required is:
15 tents * 4 meters/tent = <<15*4=60>>60 meters
2. Determine how many times the total width fits into the camping area length to find the maximum number of rows:
Total camping area length = 300 meters
Width required for one row of tents = 60 meters
Number of rows = Total camping area length / Width required for one row
Number of rows = 300 meters / 60 meters = <<300/60=5>>5
Therefore, Mei-Ling and her friends can make 5 rows of tents.

Anaís is planning a road trip from Mexico City to Guadalajara. If her car's gas tank is 3/4 full and the total capacity is 60 liters, how many liters of gas does she have for the trip? | To find out how many liters of gas Anaís has for the trip, we need to calculate 3/4 of the total capacity of her car's gas tank.
1. First, let's identify the total capacity of the gas tank, which is given as 60 liters.
2. Now, we need to find 3/4 of this total capacity:
3/4 of 60 liters = 3/4 * 60 = <<3/4*60=45>>45 liters
Therefore, Anaís has 45 liters of gas for the trip.

Tomás is planning a family reunion and wants to make sure there's enough food for everyone. He's ordered 3 large pizzas that are cut into 16 slices each and 2 smaller pizzas that are cut into 8 slices each. If 15 family members will be attending and each person eats an average of 2 slices, will Tomás have enough pizza for everyone? | To solve this problem, let's calculate the total number of slices Tom\u00e1s has ordered and compare it to the total number of slices needed for the family members.
1. Calculate the total number of slices from the large pizzas:
3 large pizzas * 16 slices per pizza = <<3*16=48>>48 slices
2. Calculate the total number of slices from the smaller pizzas:
2 smaller pizzas * 8 slices per pizza = <<2*8=16>>16 slices
3. Calculate the total number of slices Tom\u00e1s has ordered:
48 slices from large pizzas + 16 slices from smaller pizzas = <<48+16=64>>64 slices
4. Calculate the total number of slices needed for the family members:
15 family members * 2 slices per member = <<15*2=30>>30 slices
5. Compare the total number of slices Tom\u00e1s has ordered to the total number of slices needed:
64 slices ordered > 30 slices needed
Therefore, Tom\u00e1s will have enough pizza for everyone.
Since the question asks if there will be enough pizza and not for a specific number, the answer is based on the comparison rather than a specific numeric value, but to follow the format and provide a numeric answer that represents "yes" in a numeric format, we'll assign 1 for yes and 0 for no.

During a soccer match in the German Bundesliga, the home team, Bayern Munich, has a 60% chance of scoring a goal in the first half and a 40% chance in the second half. If they score a goal in the first half, their chances of winning increase to 80%, but if they score in the second half, their chances of winning decrease to 30%. What is the overall probability that Bayern Munich will score a goal and win the match? | To find the overall probability that Bayern Munich will score a goal and win the match, we need to consider the probabilities of scoring in each half and the corresponding chances of winning.
1. Probability of scoring in the first half and winning:
- Probability of scoring in the first half = 60% = 0.6
- If they score in the first half, the probability of winning = 80% = 0.8
- Combined probability for this scenario = 0.6 * 0.8 = <<0.6 * 0.8 = 0.48>>
2. Probability of scoring in the second half and winning:
- Probability of scoring in the second half = 40% = 0.4
- If they score in the second half, the probability of winning = 30% = 0.3
- Combined probability for this scenario = 0.4 * 0.3 = <<0.4 * 0.3 = 0.12>>
3. Since these are mutually exclusive events (Bayern Munich can't score in both halves in the context of this question as it asks for the overall probability of scoring a goal and winning, implying a single goal scenario), we add the probabilities of the two scenarios:
Overall probability = Probability of scoring in the first half and winning + Probability of scoring in the second half and winning
Overall probability = 0.48 + 0.12 = <<0.48 + 0.12 = 0.6>>
Therefore, the overall probability that Bayern Munich will score a goal and win the match is 60%.

Maya is planning a road trip from New York to Los Angeles. The distance between the two cities is approximately 2,796 miles. If Maya drives at an average speed of 60 miles per hour for the first 1,200 miles, and then at an average speed of 70 miles per hour for the remaining distance, how many hours will it take her to complete the trip? | To find out how many hours Maya will need to complete her trip, let's break down the problem into steps:
1. Calculate the time it takes to drive the first 1,200 miles at an average speed of 60 miles per hour:
Time = Distance / Speed
Time = 1,200 miles / 60 miles per hour
<<1200 / 60 = 20>> hours
2. Calculate the remaining distance after driving the first 1,200 miles:
Remaining distance = Total distance - Distance driven
Remaining distance = 2,796 miles - 1,200 miles
<<2796 - 1200 = 1596>> miles
3. Calculate the time it takes to drive the remaining distance at an average speed of 70 miles per hour:
Time = Distance / Speed
Time = 1,596 miles / 70 miles per hour
<<1596 / 70 = 22.8>> hours
4. Add the time it took to drive the first 1,200 miles and the time it takes to drive the remaining distance to find the total time:
Total time = Time for the first part + Time for the second part
Total time = 20 hours + 22.8 hours
<<20 + 22.8 = 42.8>> hours
Therefore, Maya will need approximately 42.8 hours to complete her trip from New York to Los Angeles.

Alejandro plans a road trip from his hometown in New Mexico to visit his family in Texas for the holidays, covering a total distance of 760 miles. His car's fuel efficiency is 25 miles per gallon. Gas costs $2.75 per gallon. If Alejandro has a 10% discount coupon for gas, how much will he spend on fuel for the entire trip? | Let's break this down step by step:
1. First, we need to calculate how many gallons of gas Alejandro will use for the trip. We can do this by dividing the total distance by the car's fuel efficiency:
Total gallons = Total distance / Fuel efficiency
Total gallons = 760 miles / 25 miles/gallon = <<760 / 25 = 30.4>>30.4 gallons
2. Next, we calculate the total cost of the gas without the discount:
Total cost without discount = Total gallons * Cost per gallon
Total cost without discount = 30.4 gallons * $2.75/gallon = <<30.4 * 2.75 = 83.6>>$83.6
3. Now, we apply the 10% discount to the total cost:
Discount amount = 10% of Total cost without discount
Discount amount = 0.10 * $83.6 = <<0.10 * 83.6 = 8.36>>$8.36
4. Finally, we subtract the discount amount from the total cost without discount to find the final amount Alejandro will spend on fuel:
Total cost with discount = Total cost without discount - Discount amount
Total cost with discount = $83.6 - $8.36 = <<83.6 - 8.36 = 75.24>>$75.24
Therefore, Alejandro will spend $75.24 on fuel for the entire trip.
#### 75.24 |
Maya is traveling from New York to Los Angeles on a train. The distance between the two cities is 2,796 miles. If the train travels at a constant speed of 60 miles per hour for the first 6 hours, then at 70 miles per hour for the remaining distance, how many hours will the entire trip take? | Let's break this down step by step:
1. First, calculate the distance covered in the first 6 hours:
Distance = Speed * Time = 60 * 6 = <<60*6=360>>360 miles
2. Subtract this distance from the total distance to find the remaining distance:
Remaining distance = Total distance - Distance covered = 2796 - 360 = <<2796-360=2436>>2436 miles
3. Now, calculate the time taken to cover the remaining distance at 70 miles per hour:
Time = Distance / Speed = 2436 / 70 = <<2436/70=34.8>>34.8 hours
4. Add the time taken for the first part and the second part to find the total time for the entire trip:
Total time = 6 + 34.8 = <<6+34.8=40.8>>40.8 hours
Therefore, the entire trip will take 40.8 hours.

Ayşe observes that her pet rabbit, Pamuk, eats 3/4 of a carrot stick every morning and her pet turtle, Yavuz, eats 1/6 of a carrot stick. If she has 12 carrot sticks, how many days will they last for both pets? | Let's solve this step by step:
1. Calculate how much of a carrot stick both pets eat together each morning:
Ay\u015fe's rabbit, Pamuk, eats 3/4 of a carrot stick and her turtle, Yavuz, eats 1/6 of a carrot stick.
First, find a common denominator for 4 and 6, which is 12.
Convert 3/4 to have a denominator of 12: 3/4 = 9/12
Convert 1/6 to have a denominator of 12: 1/6 = 2/12
Now, add the fractions: 9/12 + 2/12 = <<9+2=11>>11/12
2. Since they eat 11/12 of a carrot stick each morning, we need to find out how many days 12 carrot sticks will last.
To do this, divide the total number of carrot sticks by the amount eaten each day:
12 carrot sticks / (11/12) carrot sticks per day = 12 / (11/12)
To divide by a fraction, we multiply by its reciprocal: 12 * (12/11) = <<12*12/11=13.09>>13.09 days
Since we cannot have a fraction of a day in this context, we'll round down to the nearest whole number because they can't eat a fraction of a carrot stick on the last day.
13.09 days -> 13 days
Therefore, the carrot sticks will last for 13 days for both pets.

Khalid is building a scale model of the Burj Khalifa using balsa wood. The actual height of the Burj Khalifa is 828 meters, and Khalid wants his model to be 1/1000th of the actual height. If he has a piece of balsa wood that is 1 meter long, how many centimeters will he need to cut off to make it the correct height for his model? | To solve this problem, we need to find the correct height for Khalid's model and then subtract that from the length of the balsa wood to determine how much he needs to cut off.
1. First, we need to calculate the height of the model by multiplying the actual height of the Burj Khalifa by the scale factor of 1/1000.
Model height = 828 meters * 1/1000 = <<828 * 1/1000 = 0.828>> meters
2. Since Khalid has a piece of balsa wood that is 1 meter long, and we want to find out how many centimeters he needs to cut off, we should convert the model height from meters to centimeters. There are 100 centimeters in a meter, so:
Model height in centimeters = 0.828 meters * 100 centimeters/meter = <<0.828 * 100 = 82.8>> centimeters
3. Now, to find out how many centimeters Khalid needs to cut off, we subtract the model height from the length of the balsa wood. The balsa wood is 1 meter long, which is 100 centimeters.
Length to cut off = Length of balsa wood - Model height = 100 centimeters - 82.8 centimeters = <<100 - 82.8 = 17.2>> centimeters
Therefore, Khalid needs to cut off 17.2 centimeters from the balsa wood to make it the correct height for his model.

Fatima invested 5000 AED in a wildlife conservation project in the UAE, earning an annual interest rate of 7% compounded annually. If she donates 10% of the interest earned each year to support local animal shelters, how much will she have in her account after 5 years? | Let's solve this step-by-step:
1. First, let's calculate the interest earned each year: 7% of 5000 AED = <<7/100 * 5000 = 350>>AED.
2. Fatima donates 10% of the interest, so she keeps 90% of 350 AED = <<90/100 * 350 = 315>>AED each year.
3. Now, let's calculate the amount in her account after 1 year: 5000 AED (initial) + 315 AED (interest) = <<5000 + 315 = 5315>>AED.
4. For the next 4 years, the same process repeats. To simplify, we can calculate the growth factor: 1 + 0.07 * 0.9 = <<1 + 0.07 * 0.9 = 1.063>>. We apply this factor to the current balance for each subsequent year.
5. After 5 years, the total amount will be: 5000 AED * (1.063)^5 = <<5000 * (1.063)^5 = 6786.35>>AED.
Therefore, Fatima will have approximately 6786.35 AED in her account after 5 years.

Ariella is shopping at the Carmel Market in Tel Aviv and wants to buy a combination of kilim rugs and traditional Israeli clothing to bring back as gifts. She has a budget of 850 shekels and each kilim rug costs 120 shekels, while each piece of clothing costs 75 shekels. If Ariella also has a 10% discount coupon for the total purchase, how many kilim rugs and pieces of clothing can she buy within her budget? | Let's solve this step-by-step:
1. First, let's calculate the maximum amount Ariella can spend with the 10% discount:
The discount amount is 10% of 850 shekels, which is: <<850 * 10 / 100 = 85>> shekels
So, the maximum amount she can spend after the discount is: <<850 - 85 = 765>> shekels
2. Next, let's set up equations for the total cost of kilim rugs and traditional clothing:
Let x be the number of kilim rugs and y be the number of pieces of clothing.
The cost of kilim rugs is 120x shekels and the cost of clothing is 75y shekels.
The total cost equation is: 120x + 75y ≤ 765
3. Since we want to find the maximum number of items Ariella can buy, let's find the boundary line of the inequality 120x + 75y = 765 and test points within the feasible region:
We can start by finding the x-intercept (when y = 0):
120x = 765
x = <<765 / 120 = 6.375>>
Since we can't buy a fraction of a rug, the maximum number of kilim rugs Ariella can buy is 6.
Next, let's find the y-intercept (when x = 0):
75y = 765
y = <<765 / 75 = 10.2>>
Since we can't buy a fraction of clothing, the maximum number of pieces of clothing Ariella can buy is 10.
Now, we can test a combination of 5 kilim rugs and some pieces of clothing:
120(5) + 75y = 765
600 + 75y = 765
75y = 165
y = <<165 / 75 = 2.2>>
This combination doesn't yield an integer number of pieces of clothing, so let's test another combination of 4 kilim rugs and some pieces of clothing:
120(4) + 75y = 765
480 + 75y = 765
75y = 285
y = <<285 / 75 = 3.8>>
This combination also doesn't yield an integer number of pieces of clothing, so let's test another combination of 3 kilim rugs and some pieces of clothing:
120(3) + 75y = 765
360 + 75y = 765
75y = 405
y = <<405 / 75 = 5.4>>
This combination doesn't yield an integer number of pieces of clothing, so let's test another combination of 2 kilim rugs and some pieces of clothing:
120(2) + 75y = 765
240 + 75y = 765
75y = 525
y = <<525 / 75 = 7>>
This combination yields an integer number of pieces of clothing.
Lastly, let's test a combination of 1 kilim rug and some pieces of clothing:
120(1) + 75y = 765
120 + 75y = 765
75y = 645
y = <<645 / 75 = 8.6>>
This combination doesn't yield an integer number of pieces of clothing.
So, the maximum number of items Ariella can buy within her budget is 2 kilim rugs and 7 pieces of clothing.

In the savannas of Africa, a wildlife observer notices that the ratio of antelopes to zebras is 5:7. If there are 35 zebras in the observed area, how many antelopes are there? | Let's solve this step-by-step:
1. The ratio of antelopes to zebras is given as 5:7.
2. We know there are 35 zebras in the observed area.
3. To find the number of antelopes, we can set up a proportion using the ratio and the known number of zebras:
Antelopes / Zebras = 5 / 7
Antelopes / 35 = 5 / 7
4. We can solve this proportion by cross-multiplying:
Antelopes * 7 = 35 * 5
Antelopes = (35 * 5) / 7
Antelopes = <<35 * 5 = 175>> / 7
Antelopes = <<175 / 7 = 25>>
5. Therefore, there are 25 antelopes in the observed area.

Fatima bought 3 3/4 kilograms of dates at a market in Riyadh. She gave 1 1/2 kilograms to her neighbor and then bought 2 1/4 more kilograms. What is the total weight of dates Fatima has now? | Let's solve this step-by-step:
1. Fatima initially bought 3 3/4 kilograms of dates. We need to convert the mixed number into an improper fraction for easier calculations: 3 3/4 = (3*4 + 3)/4 = 15/4 kilograms.
2. She gave 1 1/2 kilograms to her neighbor. Convert this mixed number to an improper fraction as well: 1 1/2 = (1*2 + 1)/2 = 3/2 kilograms.
3. To subtract the amount given away from the initial amount, we need a common denominator, which is 4. Convert 3/2 into a fraction with the denominator of 4: (3/2)*(2/2) = 6/4 kilograms.
4. Now subtract the amount given away from the initial amount: 15/4 - 6/4 = <<15-6=9>>9/4 kilograms.
5. Fatima then bought 2 1/4 more kilograms. Convert this mixed number to an improper fraction: 2 1/4 = (2*4 + 1)/4 = 9/4 kilograms.
6. To find the total weight of dates Fatima has now, add the remaining weight to the newly bought weight: 9/4 + 9/4 = <<9+9=18>>18/4 kilograms.
7. Simplify the fraction: 18/4 = <<18/4=4.5>>4.5 kilograms.
Therefore, the total weight of dates Fatima has now is 4.5 kilograms.

The school soccer team, the Kibera Kickers, from Nairobi, Kenya, is planning a fundraiser by selling team-branded jerseys and soccer balls. They make a profit of 500 Kenyan shillings for each jersey and 800 shillings for each soccer ball. The team has a goal to raise 60,000 shillings. If they have already sold 30 jerseys, how many soccer balls must they sell to meet their goal? | Let's solve this step by step:
1. First, calculate the total profit made from selling the jerseys:
30 jerseys * 500 shillings/jersey = <<30*500=15000>>15000 shillings
2. Subtract the profit made from jerseys from the total goal to find out how much more money they need to raise:
60000 shillings - 15000 shillings = <<60000-15000=45000>>45000 shillings
3. Determine how many soccer balls they need to sell to meet the remaining goal:
45000 shillings / 800 shillings/soccer ball = <<45000/800=56.25>>56.25 soccer balls
4. Since they cannot sell a fraction of a soccer ball, they will need to sell 57 soccer balls to meet their goal.
Therefore, the Kibera Kickers must sell 57 soccer balls to meet their goal.

Tomás is planning a road trip from his hometown of Albuquerque, New Mexico, to visit his abuela in Tucson, Arizona, which is approximately 560 miles away. His car's fuel efficiency is around 28 miles per gallon. Gasoline costs $2.75 per gallon. If Tomás has a 20% chance of encountering a sandstorm, which would reduce his car's fuel efficiency to 20 miles per gallon, what is the expected cost of gasoline for his trip? | To find the expected cost of gasoline for Tom\u00e1s' trip, we need to calculate the cost for both scenarios (with and without the sandstorm) and then find the weighted average based on the probability of the sandstorm.
1. Calculate the amount of gasoline needed without the sandstorm:
Distance to Tucson = 560 miles
Fuel efficiency = 28 miles per gallon
Gasoline needed = Total distance / Fuel efficiency = <<560 / 28 = 20>> gallons
2. Calculate the cost of gasoline without the sandstorm:
Cost per gallon = $2.75
Total cost without sandstorm = Gasoline needed * Cost per gallon = <<20 * 2.75 = 55>> dollars
3. Calculate the amount of gasoline needed with the sandstorm:
Reduced fuel efficiency = 20 miles per gallon
Gasoline needed with sandstorm = Total distance / Reduced fuel efficiency = <<560 / 20 = 28>> gallons
4. Calculate the cost of gasoline with the sandstorm:
Total cost with sandstorm = Gasoline needed with sandstorm * Cost per gallon = <<28 * 2.75 = 77>> dollars
5. Calculate the expected cost considering the probability of the sandstorm:
Probability of sandstorm = 20% = 0.2
Probability of no sandstorm = 1 - Probability of sandstorm = 1 - 0.2 = 0.8
Expected cost = (Total cost without sandstorm * Probability of no sandstorm) + (Total cost with sandstorm * Probability of sandstorm)
Expected cost = (55 * 0.8) + (77 * 0.2) = <<55 * 0.8 = 44>> + <<77 * 0.2 = 15.4>> = <<44 + 15.4 = 59.4>> dollars
Therefore, the expected cost of gasoline for Tom\u00e1s' trip is $59.4.
#### 59.4 |
Eitan and his friends are playing a game of capture the flag in the park. The probability that Eitan's team wins a round is 3/5, and the probability that they win the next round given that they won the previous round is 2/3. What is the probability that Eitan's team wins two rounds in a row? | To find the probability that Eitan's team wins two rounds in a row, we need to multiply the probability of winning the first round by the probability of winning the second round given that they won the first round.
1. Probability of winning the first round: 3/5
2. Probability of winning the second round given that they won the first round: 2/3
3. Multiply these probabilities to find the probability of winning two rounds in a row: (3/5) * (2/3) = <<(3/5)*(2/3)=2/5>>
Therefore, the probability that Eitan's team wins two rounds in a row is 2/5.

Tomer wants to cover the floor of his new room in Tel Aviv with a carpet. The room is 4 meters long and 3 meters wide. If the carpet costs 50 shekels per square meter, how much will it cost Tomer to cover the entire floor? | Let's solve this step by step:
1. First, calculate the area of the room by multiplying its length and width:
Area = length * width = <<4 * 3 = 12>> square meters
2. Now, calculate the total cost by multiplying the area by the cost per square meter of carpet:
Total cost = Area * cost per square meter = <<12 * 50 = 600>> shekels
Therefore, it will cost Tomer 600 shekels to cover the entire floor.
#### 600 |
For her Bat Mitzvah celebration, Noa's parents invested 5,000 shekels in a savings account with a 4% annual interest rate compounded annually. How much money will Noa have after 8 years? | To solve this, let's break it down step by step:
1. First, we need to calculate the annual growth factor for the investment, which is 1 plus the annual interest rate (as a decimal).
The annual interest rate as a decimal is 4% / 100% = 0.04.
So, the annual growth factor is 1 + 0.04 = <<1 + 0.04 = 1.04>>.
2. Since the interest is compounded annually, we raise the annual growth factor to the power of the number of years to find the total growth factor.
The number of years is 8, so the total growth factor is 1.04^8 = <<1.04^8 = 1.3605>>.
3. To find the total amount after 8 years, we multiply the initial investment by the total growth factor.
The initial investment is 5,000 shekels, so the total amount after 8 years is 5,000 * 1.3605 = <<5000 * 1.3605 = 6802.5>>.
Therefore, Noa will have 6,802.5 shekels after 8 years.

Nong has been planning a camping trip with her friends in the mountains of northern Thailand. She wants to make sure they have enough food for the entire trip. If they plan to spend 5 days camping and each person eats 3 meals per day, how many meals in total will Nong need to prepare for 8 campers, considering she already has 15 pre-cooked meals ready? | Let's solve this step by step:
1. First, calculate the total number of meals needed per camper for the entire trip:
Each camper eats 3 meals per day for 5 days, so the total meals per camper is 3 meals/day * 5 days = <<3*5=15>>15 meals.
2. Since there are 8 campers, the total meals needed for all campers is:
15 meals/camper * 8 campers = <<15*8=120>>120 meals.
3. Nong already has 15 pre-cooked meals, so she needs to prepare:
120 total meals - 15 pre-cooked meals = <<120-15=105>>105 more meals.
Therefore, Nong needs to prepare 105 meals for the camping trip.

Kamal is planning a camping trip with his friends in the Osun Osogbo Sacred Grove. He wants to set up a rectangular campsite with an area of 240 square meters. If the length of the campsite is 3 times its width, and he needs to put a fence around the entire area, what is the minimum length of fencing required in meters? | To find the minimum length of fencing required, we first need to determine the dimensions of the campsite. Let's denote the width of the campsite as w and the length as 3w, since the length is 3 times the width.
Given that the area of the campsite is 240 square meters, we can write the equation:
Area = length * width
240 = 3w * w
Now, let's solve for w:
3w^2 = 240
w^2 = 240 / 3
w^2 = <<240 / 3 = 80>>
w = sqrt(80)
w = <<sqrt(80) = 8.944>> meters
Since the length is 3 times the width:
length = 3w
length = 3 * 8.944
length = <<3 * 8.944 = 26.832>> meters
The perimeter of the campsite (which is the minimum length of fencing required) is the sum of all sides:
Perimeter = 2(length + width)
Perimeter = 2(26.832 + 8.944)
Perimeter = 2 * <<26.832 + 8.944 = 35.776>>
Perimeter = <<2 * 35.776 = 71.552>> meters
Therefore, the minimum length of fencing required is approximately 71.55 meters.

Ayşe observes that a group of birds visit her bird feeder every morning. If 15 birds come at 7:00 AM, 8 more birds arrive at 7:30 AM, and then 2 birds leave at 8:00 AM, how many birds are at the bird feeder at 8:00 AM? | Let's solve this step by step:
1. Initially, there are 15 birds at 7:00 AM.
2. At 7:30 AM, 8 more birds arrive, so we add these to the initial number of birds:
<<15 + 8 = 23>>
3. Then, at 8:00 AM, 2 birds leave, so we subtract these from the total number of birds present:
<<23 - 2 = 21>>
Therefore, there are 21 birds at the bird feeder at 8:00 AM.

Herr Müller observes that the ratio of birds to squirrels in the forest near his home in Berlin is 5:3. If he counts a total of 48 animals and knows that the number of birds has increased by 20% due to the new bird feeders he installed, how many squirrels are there now? | Let's solve this step by step:
1. First, we need to find the original number of birds and squirrels before the increase. We know the ratio of birds to squirrels is 5:3. Let's represent the number of birds as 5x and the number of squirrels as 3x.
2. We are given that the total number of animals (birds + squirrels) is 48. We can set up the equation:
5x + 3x = 48
Combine like terms:
8x = 48
Solve for x:
x = <<48 / 8 = 6>>
3. Now that we have the value of x, we can find the original number of birds and squirrels:
Original number of birds = 5x = 5 * 6 = <<5 * 6 = 30>>
Original number of squirrels = 3x = 3 * 6 = <<3 * 6 = 18>>
4. The number of birds has increased by 20%. We need to find the new number of birds:
Increase in birds = 20% of 30 = 0.20 * 30 = <<0.20 * 30 = 6>>
New number of birds = Original number of birds + Increase in birds = 30 + 6 = <<30 + 6 = 36>>
5. Since the number of squirrels remains the same, we only need to find the new total number of animals:
New total number of animals = New number of birds + Original number of squirrels = 36 + 18 = <<36 + 18 = 54>>
6. However, we are only asked about the number of squirrels, which has not changed.
Therefore, the number of squirrels remains the same.

Rohan's school is organizing a fair, and his class is in charge of the ring toss game. They have 5 rings of different colors - red, blue, green, yellow, and purple. The probability of winning with the red ring is 1/5, the blue ring is 1/7, the green ring is 1/3, the yellow ring is 1/4, and the purple ring is 1/6. If Rohan's friend, Aryan, plays the game 12 times with each ring, what is the total expected number of wins for Aryan? | To find the total expected number of wins for Aryan, we need to calculate the expected number of wins for each ring and then add them together. We'll start by finding the expected number of wins for each ring.
1. Red ring: The probability of winning with the red ring is 1/5. Since Aryan plays the game 12 times with the red ring, the expected number of wins is: 12 * (1/5) = <<12*(1/5)=2.4>>2.4
2. Blue ring: The probability of winning with the blue ring is 1/7. Since Aryan plays the game 12 times with the blue ring, the expected number of wins is: 12 * (1/7) = <<12*(1/7)=1.71428571>>1.71428571
3. Green ring: The probability of winning with the green ring is 1/3. Since Aryan plays the game 12 times with the green ring, the expected number of wins is: 12 * (1/3) = <<12*(1/3)=4>>4
4. Yellow ring: The probability of winning with the yellow ring is 1/4. Since Aryan plays the game 12 times with the yellow ring, the expected number of wins is: 12 * (1/4) = <<12*(1/4)=3>>3
5. Purple ring: The probability of winning with the purple ring is 1/6. Since Aryan plays the game 12 times with the purple ring, the expected number of wins is: 12 * (1/6) = <<12*(1/6)=2>>2
Now, we add the expected number of wins for each ring to find the total expected number of wins: 2.4 + 1.71428571 + 4 + 3 + 2 = <<2.4+1.71428571+4+3+2=13.11428571>>13.11428571
Rounding to two decimal places, the total expected number of wins is approximately 13.11.

Maria is making tamales for her family's holiday dinner. The recipe calls for a ratio of 2 cups of masa harina to 3 cups of pork filling. If Maria has 6 cups of masa harina, how many cups of pork filling should she use? | To find out how many cups of pork filling Maria should use, let's follow the ratio given in the recipe.
1. The ratio of masa harina to pork filling is 2:3. This means for every 2 cups of masa harina, 3 cups of pork filling are needed.
2. Maria has 6 cups of masa harina. To find out how many cups of pork filling she needs, we first determine the multiplier used to scale up from 2 cups of masa harina to 6 cups. This is done by dividing the amount of masa harina Maria has by the amount of masa harina in the ratio:
6 cups (Maria's masa harina) / 2 cups (ratio's masa harina) = <<6/2=3>>3
3. Now that we know the multiplier is 3, we apply this to the amount of pork filling in the ratio to find out how much pork filling Maria needs:
3 cups (pork filling in the ratio) * 3 (multiplier) = <<3*3=9>>9 cups
Therefore, Maria should use 9 cups of pork filling for her tamales.

Akua has 15 shirts in her closet, and she wants to randomly select 3 to wear during the upcoming week. If 7 of the shirts are blue, 4 are red, and the rest are green, what is the probability that she selects exactly 2 blue shirts and 1 green shirt? | Let's solve this step by step:
1. First, we need to find the total number of ways Akua can select 3 shirts from 15. This can be calculated using the combination formula: C(n, r) = n! / (r! * (n-r)!)
Here, n = 15 (total shirts), r = 3 (shirts to select)
So, C(15, 3) = 15! / (3! * (15-3)!)
= 15! / (3! * 12!)
= (15 * 14 * 13) / (3 * 2 * 1)
= <<15 * 14 * 13 / (3 * 2 * 1) = 455>> ways
2. Next, we need to find the number of favorable outcomes, i.e., selecting exactly 2 blue shirts and 1 green shirt.
There are 7 blue shirts and 4 green shirts. The number of ways to choose 2 blue shirts from 7 is C(7, 2) and the number of ways to choose 1 green shirt from 4 is C(4, 1).
So, C(7, 2) = 7! / (2! * (7-2)!)
= 7! / (2! * 5!)
= (7 * 6) / (2 * 1)
= <<7 * 6 / (2 * 1) = 21>> ways
And C(4, 1) = 4 ways
The total number of favorable outcomes is the product of these two: 21 * 4 = <<21 * 4 = 84>> ways
3. Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of outcomes: Probability = 84 / 455 = <<84 / 455 = 0.1844>>
Therefore, the probability that Akua selects exactly 2 blue shirts and 1 green shirt is approximately 0.1844 or 18.44%.
#### 0.1844 |
At the Toronto Zoo, the number of visitors increased by 15% from April to May and then decreased by 8% from May to June. If there were 2500 visitors in April, how many visitors were there in June? | Let's solve this step by step:
1. First, calculate the increase in visitors from April to May:
15% of 2500 = <<15 * 2500 / 100 = 375>>
Total visitors in May = 2500 + 375 = <<2500 + 375 = 2875>>
2. Then, calculate the decrease in visitors from May to June:
8% of 2875 = <<8 * 2875 / 100 = 230>>
Total visitors in June = 2875 - 230 = <<2875 - 230 = 2645>>
Therefore, there were 2645 visitors in June.

Akua is preparing a traditional Ghanaian dish, groundnut soup, for her family gathering. The recipe serves 8 people and requires 2 cups of groundnuts, 1 cup of vegetables, and 3 cups of water. If she wants to serve 24 people, and the ratio of groundnuts to vegetables to water must remain the same, how many cups of each ingredient will she need in total? | Let's solve this step by step:
1. First, we need to find the scaling factor to adjust the recipe from 8 people to 24 people.
The scaling factor is the ratio of the new number of people to the original number: 24 / 8 = <<24/8=3>>3
2. Since the ratio of ingredients must remain the same, we multiply each ingredient by the scaling factor to find the new amount needed.
For groundnuts: 2 cups * 3 = <<2*3=6>>6 cups
For vegetables: 1 cup * 3 = <<1*3=3>>3 cups
For water: 3 cups * 3 = <<3*3=9>>9 cups
3. To find the total amount of ingredients needed, we add the amounts of groundnuts, vegetables, and water together:
Total = 6 cups + 3 cups + 9 cups = <<6+3+9=18>>18 cups
Therefore, Akua will need a total of 18 cups of ingredients.

During a Bastille Day celebration in France, a bakery offers a special discount on its famous croissants. Initially, the bakery gives a 15% discount on all purchases over 20 croissants. Later in the day, it announces an additional 5% off for customers who buy at least 30 croissants. If Colette buys 35 croissants originally priced at 2 euros each, how much will she pay after both discounts are applied? | Let's solve this step by step:
1. Calculate the total cost before any discounts:
Price per croissant = 2 euros
Number of croissants = 35
Total cost = Price per croissant * Number of croissants = <<2*35=70>>70 euros
2. Calculate the cost after the initial 15% discount:
Discount amount = 15% of 70 euros = <<15/100*70=10.5>>10.5 euros
Cost after first discount = Total cost - Discount amount = <<70-10.5=59.5>>59.5 euros
3. Calculate the cost after the additional 5% discount for buying at least 30 croissants:
Additional discount = 5% of 59.5 euros = <<5/100*59.5=2.975>>2.975 euros
Final cost = Cost after first discount - Additional discount = <<59.5-2.975=56.525>>56.525 euros
Therefore, Colette will pay approximately 56.53 euros after both discounts are applied.

Luana observes that a certain species of bird in the Brazilian rainforest lays an average of 5 eggs per nest. If she finds 8 nests in her backyard, how many eggs can she expect to find in total? | To find the total number of eggs Luana can expect to find, we need to multiply the average number of eggs per nest by the number of nests she finds.
1. First, we identify the average number of eggs per nest, which is 5 eggs.
2. Then, we identify the number of nests found, which is 8 nests.
3. Multiply the average number of eggs per nest by the number of nests to find the total number of eggs:
<<5 * 8 = 40>>
Therefore, Luana can expect to find a total of 40 eggs.

Tomás went on a hike and recorded the distance he traveled every hour. His distances were 2.5 miles, 3.2 miles, 2.8 miles, 3.5 miles, and 2.2 miles. What is the total distance Tomás hiked? | To find the total distance Tom\u00e1s hiked, we need to add up all the distances he recorded every hour.
1. Start by adding the first two distances: 2.5 miles + 3.2 miles = <<2.5+3.2=5.7>>5.7 miles
2. Add the third distance to the previous total: 5.7 miles + 2.8 miles = <<5.7+2.8=8.5>>8.5 miles
3. Add the fourth distance to the new total: 8.5 miles + 3.5 miles = <<8.5+3.5=12>>12 miles
4. Finally, add the last distance to get the total distance: 12 miles + 2.2 miles = <<12+2.2=14.2>>14.2 miles
Therefore, the total distance Tom\u00e1s hiked is 14.2 miles.

Ayşe, a 6th-grade student at a Turkish school, is organizing a bake sale to raise funds for her class. She bakes 48 cookies and her friend, Emre, bakes 72 cookies. If they want to package the cookies in bags that contain 6 cookies each, how many bags can they make in total? | Let's solve this step by step:
1. First, calculate the total number of cookies Ay\u015fe and Emre baked:
Ay\u015fe's cookies: 48
Emre's cookies: 72
Total cookies = 48 + 72 = <<48 + 72 = 120>>
2. Since they want to package the cookies in bags of 6, we need to divide the total number of cookies by 6:
Total bags = Total cookies / 6 = 120 / 6 = <<120 / 6 = 20>>
Therefore, Ay\u015fe and Emre can make 20 bags of cookies in total.
#### 20 |
Ayşe's family is planning a trip to Istanbul. They want to visit the Hagia Sophia, Topkapi Palace, and the Basilica Cistern. The ticket prices are 40, 30, and 20 Turkish Lira respectively. If they also need to pay a 10% tax on the total ticket price, how much will they pay in total for the three attractions? | To find the total cost, we need to add the ticket prices and then apply the tax.
1. Add the ticket prices for the three attractions: 40 + 30 + 20 = <<40+30+20=90>>90 Turkish Lira
2. Calculate the tax amount: 10% of 90 = <<10*90/100=9>>9 Turkish Lira
3. Add the tax to the total ticket price: 90 + 9 = <<90+9=99>>99 Turkish Lira
Therefore, Ay\u015fe's family will pay 99 Turkish Lira in total for the three attractions.

Mei has been saving money for a new bike and has $120 in her savings account. She wants to buy a bike that costs $180. Mei's parents have agreed to give her an allowance of $5 per week for doing chores. However, she also spends $2 per week on snacks. How many weeks will Mei need to save her allowance in order to have enough money to buy the bike? | Let's solve this step-by-step:
1. Mei starts with $120 and needs $180 for the bike. To find out how much more money she needs, we subtract the initial amount from the cost of the bike:
$180 - $120 = $<<180-120=60>>60
2. Mei receives $5 per week but spends $2 on snacks, so her net savings per week are:
$5 - $2 = $<<5-2=3>>3
3. To find out how many weeks it will take Mei to save $60, we divide the amount needed by her net savings per week:
$60 / $3 = <<60/3=20>>20 weeks
Therefore, Mei needs to save her allowance for 20 weeks to buy the bike.

Ayşe is planning a trip from Istanbul to Antalya. If the population of Antalya is growing at a rate of 5% per year and the current population is 2.5 million, what will be the population of Antalya after 2 years? | Let's break down the problem step by step:
1. First, we need to calculate the growth rate after 1 year:
Growth rate = 5% of 2,500,000 = <<5/100 * 2500000 = 125000>>
Population after 1 year = 2,500,000 + 125,000 = <<2500000 + 125000 = 2625000>>
2. Now, we calculate the growth rate after the second year based on the population after the first year:
Growth rate = 5% of 2,625,000 = <<5/100 * 2625000 = 131250>>
Population after 2 years = 2,625,000 + 131,250 = <<2625000 + 131250 = 2756250>>
Therefore, the population of Antalya after 2 years will be 2,756,250.

Ivan is observing birds at a nature reserve near Moscow. He notices that 60% of the birds are sparrows, and 25% of the sparrows have distinctive white stripes on their heads. If Ivan sees 48 birds with white stripes, how many birds are at the nature reserve in total? | Let's solve this step by step:
1. First, we need to find the total number of sparrows. Since 25% of the sparrows have white stripes, and Ivan sees 48 birds with white stripes, we can set up the equation:
25% of the total sparrows = 48
To find the total number of sparrows, we can convert the percentage to a decimal and solve for the total:
0.25 * total sparrows = 48
total sparrows = 48 / 0.25
<<48 / 0.25 = 192>>
2. Now that we know there are 192 sparrows, and sparrows make up 60% of the total birds, we can find the total number of birds:
60% of the total birds = 192
To find the total, we can convert the percentage to a decimal and solve for the total:
0.6 * total birds = 192
total birds = 192 / 0.6
<<192 / 0.6 = 320>>
Therefore, there are 320 birds at the nature reserve in total.
#### 320 |
Hans has 150 euros to spend on school supplies. He needs to buy 5 notebooks that cost 8 euros each, a calculator for 25 euros, and a backpack that costs 30 euros. There is a discount of 10% on the total purchase if he buys all the items together. However, he also has a coupon for 20% off on the calculator. How much money will Hans have left after making the purchase? | To find out how much money Hans will have left after making the purchase, let's calculate the total cost first.
1. Calculate the total cost of the notebooks:
5 notebooks * 8 euros each = <<5 * 8 = 40>>40 euros
2. Calculate the discounted price of the calculator:
Original price = 25 euros
Discount = 20% of 25 euros = <<20/100 * 25 = 5>>5 euros
Discounted price = Original price - Discount = 25 - 5 = <<25 - 5 = 20>>20 euros
3. Add the cost of the backpack:
30 euros
4. Calculate the total cost before the 10% discount:
Total cost = Cost of notebooks + Cost of calculator + Cost of backpack
= 40 euros + 20 euros + 30 euros
= <<40 + 20 + 30 = 90>>90 euros
5. Calculate the 10% discount on the total purchase:
Discount = 10% of 90 euros = <<10/100 * 90 = 9>>9 euros
6. Calculate the final total cost after the discount:
Final total cost = Total cost - Discount
= 90 euros - 9 euros
= <<90 - 9 = 81>>81 euros
7. Calculate how much money Hans will have left after the purchase:
Money left = Initial money - Final total cost
= 150 euros - 81 euros
= <<150 - 81 = 69>>69 euros
Therefore, Hans will have 69 euros left after making the purchase.

Tom is planning a road trip from New York to Los Angeles. He has a map that shows the distances between major cities along his route. From New York to Chicago is 790 miles, from Chicago to Denver is 920 miles, and from Denver to Los Angeles is 1010 miles. If Tom's car gets an average of 30 miles per gallon, and gas costs $2.75 per gallon, how much will he spend on gas for the entire trip? | Let's solve this step by step:
1. First, we need to calculate the total distance of the trip by adding the distances between each city:
Total distance = Distance from New York to Chicago + Distance from Chicago to Denver + Distance from Denver to Los Angeles
Total distance = 790 + 920 + 1010
<<790 + 920 + 1010 = 2720>>
Total distance = 2720 miles
2. Next, we calculate how many gallons of gas Tom will use for the entire trip:
Total gallons = Total distance / Average miles per gallon
Total gallons = 2720 / 30
<<2720 / 30 = 90.67>>
Total gallons = 90.67 gallons
3. Then, we find the total cost of gas by multiplying the total gallons by the cost per gallon:
Total gas cost = Total gallons * Cost per gallon
Total gas cost = 90.67 * 2.75
<<90.67 * 2.75 = 249.34>>
Total gas cost = $249.34
Therefore, Tom will spend $249.34 on gas for the entire trip.

Ahmet observes that a local bird sanctuary has a 15% increase in the number of migratory birds visiting each year. If there were 250 birds in the sanctuary last year, and 30 birds decided to stay permanently, how many migratory birds can Ahmet expect to see this year, given that the sanctuary can only support a maximum of 400 birds? | Let's solve this step-by-step:
1. First, calculate the increase in the number of migratory birds from last year to this year:
Increase = 15% of 250 = <<15/100 * 250 = 37.5>>
2. Since the increase needs to be a whole number of birds, we round down to 37 birds because you cannot have a fraction of a bird.
3. Calculate the total number of migratory birds expected this year:
Total migratory birds = 250 + 37 = <<250 + 37 = 287>>
4. Considering that 30 birds decided to stay permanently, these birds are not migratory, so they do not affect the count of migratory birds Ahmet expects to see this year.
5. Lastly, we compare the total number of migratory birds expected to the sanctuary's capacity of 400 birds. Since 287 is less than 400, Ahmet can expect to see all 287 migratory birds this year without the sanctuary reaching its maximum capacity.
Therefore, Ahmet can expect to see 287 migratory birds this year.

In a Nigerian football league, the ratio of goals scored by the Super Eagles to those scored by the Flying Antelopes is 5:3. If the Super Eagles scored 25 goals, how many goals did the Flying Antelopes score? | Let's solve this step by step:
1. The ratio of goals scored by the Super Eagles to those scored by the Flying Antelopes is given as 5:3.
2. We are told the Super Eagles scored 25 goals. We need to find how many goals the Flying Antelopes scored.
3. To do this, we first determine the factor by which the ratio 5:3 needs to be multiplied to get 25 goals for the Super Eagles.
Since the Super Eagles' goals are represented by the number 5 in the ratio, we find this factor by dividing 25 by 5:
25 / 5 = <<25/5=5>>5
4. Now, we multiply the number of goals scored by the Flying Antelopes in the ratio (3) by this factor to find out how many goals they scored:
3 * 5 = <<3*5=15>>15
Therefore, the Flying Antelopes scored 15 goals.

Ayşe and her family are planning a traditional Turkish dinner for 15 guests. They want to serve a combination of vegetarian and meat dishes in a 3:5 ratio. If they decide to serve 3 vegetarian dishes, how many meat dishes should they prepare to maintain the desired ratio? | Let's solve this step by step:
1. First, understand the given ratio of vegetarian to meat dishes, which is 3:5.
2. Since Ay\u015fe's family decides to serve 3 vegetarian dishes, we need to find how many meat dishes (let's call this number x) will maintain the 3:5 ratio.
3. Set up the proportion based on the ratio: 3/5 = 3/x
4. Cross multiply to solve for x: 3*x = 3*5
<<3*5=15>>
5. This simplifies to 3x = 15.
6. Solve for x by dividing both sides by 3: x = 15/3
<<15/3=5>>
7. So, x equals 5, meaning they should prepare 5 meat dishes to maintain the desired ratio.
8. Therefore, Ay\u015fe and her family should prepare 5 meat dishes.

Mrs. Thompson, a Canadian high school teacher, is planning a school garden in the shape of a rectangular prism with a length of 15 meters, a width of 8 meters, and a height of 2 meters. If a path that is 2 meters wide is built around the garden, what is the area of the path? | To find the area of the path, we need to find the area of the larger rectangular prism that includes the path and subtract the area of the garden itself.
1. First, let's find the dimensions of the larger rectangular prism. Since the path is 2 meters wide, we add 2 meters to the length and width of the garden:
Length of larger prism = 15 meters + 2 meters + 2 meters = <<15+2+2=19>>19 meters
Width of larger prism = 8 meters + 2 meters + 2 meters = <<8+2+2=12>>12 meters
2. The area of the larger rectangular prism is:
Area of larger prism = Length * Width = 19 meters * 12 meters = <<19*12=228>>228 square meters
3. Now, let's find the area of the garden itself:
Area of garden = Length * Width = 15 meters * 8 meters = <<15*8=120>>120 square meters
4. Since the path is 2 meters wide and its height is the same as the garden's height, the area of the path's sides can be calculated by multiplying the path's width by the garden's height and then multiplying by 2 (since there are two sides of length and two sides of width):
Area of path's sides = 2 * (2 meters * 2 meters * 15 meters + 2 meters * 2 meters * 8 meters) = 2 * (60 + 32) = 2 * 92 = <<2*92=184>>184 square meters
5. To find the total area of the path, we subtract the area of the garden from the area of the larger prism and add the area of the path's sides:
Total area of path = Area of larger prism - Area of garden + Area of path's sides = 228 - 120 + 184 = <<228-120+184=292>>292 square meters
However, this includes the area of the path's sides twice (the top and bottom areas), so we need to correct this by subtracting the area of the path's sides that overlap with the top and bottom of the larger prism:
Overlapping area = 2 * (15 meters * 2 meters + 8 meters * 2 meters) = 2 * (30 + 16) = 2 * 46 = <<2*46=92>>92 square meters
6. Correct the total area of the path by subtracting the overlapping area:
Corrected total area of path = Total area of path - Overlapping area = 292 - 92 = <<292-92=200>>200 square meters
7. Therefore, the area of the path is 200 square meters.

Ivan and his friends are organizing a tree-planting event in Moscow. They want to plant trees in a pattern such that each row has twice as many trees as the previous row. If they start with 5 trees in the first row and plant 8 rows in total, how many trees will they have planted in total? | Let's solve this step-by-step:
1. The number of trees in each row follows a pattern where each row has twice as many trees as the previous row. The first row has 5 trees.
2. To find the number of trees in the second row, we multiply the number of trees in the first row by 2:
<<5 * 2 = 10>>
3. Following this pattern, we calculate the number of trees for each subsequent row:
Row 3: 10 * 2 = <<10 * 2 = 20>>
Row 4: 20 * 2 = <<20 * 2 = 40>>
Row 5: 40 * 2 = <<40 * 2 = 80>>
Row 6: 80 * 2 = <<80 * 2 = 160>>
Row 7: 160 * 2 = <<160 * 2 = 320>>
Row 8: 320 * 2 = <<320 * 2 = 640>>
4. To find the total number of trees planted, we add up the number of trees in each row:
Total = 5 + 10 + 20 + 40 + 80 + 160 + 320 + 640 = <<5 + 10 + 20 + 40 + 80 + 160 + 320 + 640 = 1275>>
Therefore, Ivan and his friends will have planted a total of 1275 trees.
#### 1275 |
