[Question]Sarah is buying Christmas presents for her family. She starts her shopping with a certain amount of money. She buys 2 toy cars for $11 each for her sons. She buys a scarf for $10 for her mother. Then she buys a beanie for $14 for her brother. If she has $7 remaining after purchasing the beanie, how much money did she start with?
[Answer]Before purchasing the beanie, Sarah has $7 + $14 = $21. Before purchasing the scarf, Sarah has $21 + $10 = $31. The total cost of the toy cars is 2 * $11 = $22. Before purchasing the toy cars, Sarah has $31 + $22 = $53. The answer is 53.
Q: Barry, Thomas and Emmanuel are to share a jar of 200 jelly beans. If Thomas takes 10%, and Barry and Emmanuel are to share the remainder in the ratio 4:5 respectively, how many jelly beans will Emmanuel get?
A: 10% of 200 jelly beans is (10 / 100) * 200 = 20 jelly beans. Thomas takes 20 jelly beans leaving 200 - 20 = 180 jelly beans. 180 jelly beans are to be shared in the ratio 4:5 so each share is 180 / (4 + 5) = 20 jelly beans. Emmanuel gets 5 shares which is 5 * 20 = 100. The answer is 100.

[Question]John has been having trouble sleeping lately. In the past week he was only able to get 3 hours of sleep on 2 of the days and on the remaining days he was only able to get 60% of the recommended 8 hours of sleep. How much sleep did he get this week?
[Answer]For the 2 days he gets 2 * 3 = 6 hours. He gets 60% of the recommended amount for 7 - 2 = 5 days. On those days he gets 8 * .6 = 4.8 hours. So he gets 5 * 4.8 = 24 hours. So he gets a total of 24 + 6 = 30 hours of sleep. The answer is 30.
Q: Trey is raising money for a new bike that costs $112. He plans to spend the next two weeks selling bracelets for $1 each. On average, how many bracelets does he need to sell each day?
A: He needs to sell 112 bracelets because 112 divided by 1 equals 112. He has 14 days to sell bracelets because there are seven days in a week and he has two weeks seven times 2 equals 14. He has to sell 8 bracelets a day because 112 divided by 14 equals 8. The answer is 8.
Question: In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards?
Answer:
The difference in cubic yards between the two cities is 9000 - 6400 = 2600 cubic yards. Since the number of people living in a city per cubic yard is 80, there are 80 * 2600 = 208000 more people living in a city with 9000 cubic yards than a city with 6400 cubic yards. The answer is 208000.
