Q: Thomas owns 200 books. He decides to sell them and use the money to buy records. Each book sells for $1.5. A record costs $3. If he buys 75 records, how much money does he have left over?
A: He makes $300 selling the books because 200 x 1.5 = 300. He spends $225 on records because 75 x 3 = 225. He has $75 left because 300 - 225 = 75. The answer is 75.
Question: Each slice of cheesecake contains 350 calories. If there are a total of 2800 calories in every cheesecake, and Kiley ate 25% of the cheesecake, how many slices of cheesecake did Kiley eat?
Answer: If there are 2800 calories in every cheesecake, and each slice of cheesecake contains 350 calories, then the cheesecake has 2800 / 350 = 8 slices. If Kiley ate 25% of the cheesecake, then she ate 8 * 0.25 = 2 slices of cake. The answer is 2.
[Question]Geric had twice as many bills as Kyla who has 2 fewer bills than Jessa. After giving 3 bills to Geric, Jessa has 7 bills left. How many bills did Geric have at the beginning?
[Answer]Jessa had 7 + 3 = 10 bills before she gave 3 to Geric. Kyla had 10 - 2 = 8 bills. So, Geric had 8 x 2 = 16 bills. The answer is 16.
Q: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
A: First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds. The answer is 270.
Question: Hammond carves life-sized statues out of marble. His latest set of four statues started with an 80-pound block of marble. The first statue he carved weighed 10 pounds. The second statue weighed 18. The remaining two statues weighed the same amount. The marble he discarded after carving it off the statues weighed 22 pounds. How much did each of the remaining statues Hammond carved weigh?
Answer: Hammond’s statues weighed 80 - 22 = 58 pounds after the discarded marble was carved off. Minus the first statue, the statues weighed 58 - 10 = 48 pounds. Minus the second statue, the statues weighed 48 - 18 = 30 pounds. The remaining two statues weighed the same amount, so each weighed 30 / 2 = 15 pounds. The answer is 15.
Q: George bought some food for his trip: a bottle of juice, a sandwich, and a bottle of milk. The sandwich was for $4, and the juice was two times more expensive. The bottle of milk cost was 75% of the total cost of the sandwich and juice. How much did George pay for his food?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The juice was two times more expensive than the sandwich, so it was 4 * 2 = $8. The juice and the sandwich in total were a cost of 4 + 8 = $12. So the cost of one bottle of milk was 75 / 100 * 12 = $9. In total for all the food, George paid 12 + 9 = $21. The answer is 21.
