Question: Mell went to a cafeteria to spend some time with her friends. She ordered two cups of coffee and one piece of cake. Two of her friends ordered the same, but each of them also bought a bowl of ice cream. One cup of coffee is $4, one piece of cake is $7, and a bowl of ice cream is $3. How much money did Mell and her friends need to pay at the cafeteria?
Answer: Mell's friends bought two bowls of ice cream, so that was a cost of 2 * 3 = $6. They all three bought two cups of coffee each, so they ordered 2 * 3 = 6 cups of coffee in total. The cost of the coffee was therefore 6 * 4 = $24. All her friends bought one piece of cake each, so the cost of it in total was 3 * 7 = $21. Mell and her friends spent in total 6 + 24 + 21 = $51 at the cafeteria. The answer is 51.
[Question]A baker sells pastries for $5 and works 7 days a week. On Monday he sold 2. Every day the number of sales increases by 1 compared to the previous day. On average, how many pastries does he sell on each day of the week?
[Answer]You know from the statement that on Monday he sells 2 pastries, so on Tuesday he sells 3, Wednesday 4, Thursday 5, Friday 6, Saturday 7 and Sunday 8 pastries. So the average value is (2 + 3 + 4 + 5 + 6 + 7 + 8) pastries / 7 days. The baker sells, on average, 35 / 7 = 5 pastries / day for 1 week. The answer is 5.
Q: Jason has six fish in his aquarium. He realizes that every day the number of fish doubles. On the third day he takes out one-third of the fish. On the fifth day he takes out one-fourth of the fish. On the seventh day he adds 15 more fish. How many fish in total does he have?
A: Start by finding how many fish were in the aquarium on the third day 6 * 2 * 2 = 24. On day three, Jason took out one - third of the fish 24 / 3 = 8. So at the end of day three, he has 24 - 8 = 16 fish. On day five he has 16 * 2 * 2 = 64 fish, but he takes out one - fourth. So he took out 64 / 4 = 16 fishes. So at the end of day five, he has 64 - 16 = 48 fish. On day seven he has 48 * 2 * 2 = 192 fish. He adds in 15 more, so he has 192 + 15 = 207 fish in total. The answer is 207.
Question: Percy wants to save up for a new PlayStation, which costs $500. He gets $200 on his birthday and $150 at Christmas. To make the rest of the money, he's going to sell his old PlayStation games for $7.5 each. How many games does he need to sell to reach his goal?
Answer: He needs to earn $150 more dollars because 500 - 200 - 150 = 150. He needs to sell 20 games because 150 / 7.5 = 20. The answer is 20.
[Question]Rick took off on a road trip for the summer. He traveled to the first destination on his trip, and then from there, he traveled twice the distance to this second destination. The third point on his trip was 40 miles away, which was half the distance he traveled from the beginning to his first destination. The final destination took twice the amount of driving of all the other legs put together. How many miles in total did he travel across all the legs of the trip?
[Answer]If the third leg of Rick's trip was half the distance of the first leg, was 40 miles, this means the first leg was 40 * 2 = 80 miles long. If the second leg of the trip was twice the distance of the first leg, that means it was 80 * 2 = 160 miles long. If the fourth leg was equal in distance to the total amount traveled across the first 3 legs, that means it was equal to 40 + 80 + 160 = 280 miles long. This means in total Rick traveled 280 + 280 = 560 miles. The answer is 560.
