Q: John is trying to save money by buying cheap calorie-dense food. He can buy 10 burritos for $6 that have 120 calories each. He could also buy 5 burgers that are 400 calories each for $8. How many more calories per dollar does he get from the burgers?
A: The burritos have 10 * 120 = 1200 calories. That means he gets 1200 / 6 = 200 calories per dollar. The burgers get 5 * 400 = 2000 calories. So he gets 2000 / 8 = 250 calories per dollar. So he gets 250 - 200 = 50 more calories per dollar from the burgers. The answer is 50.
Question: Jon makes 3/4's the salary that Karen makes. John makes $3000 per month. How long will it take him to make the same amount of money that Karen does in 3 months?
Answer: Karen makes $3000 / (3 / 4) = $4000 per month. In three months, Karen would make a total of $4000 * 3 = $12000. To make the same amount of money John would need to work $12000 / $3000 = 4 months. The answer is 4.
[Question]While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all?
[Answer]If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = 120 carriages. Together, Flying Scotsman and Norwich had 120 + 100 = 220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = 110 carriages. Together, Euston and Norfolk had 110 + 130 = 240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = 460 carriages. The answer is 460.
Q: In the beginning, Justine had 10 more rubber bands than Bailey but 2 fewer bands than Ylona. Bailey decided to give two bands each to Justine and Ylona so that he is left with only 8 rubber bands. How many rubber bands did Ylona have in the beginning?
A: Bailey gave 2 + 2 = 4 bands. So Bailey had 8 + 4 = 12 bands in the beginning. Justine had 12 + 10 = 22 bands in the beginning. Thus, Ylona had 22 + 2 = 24 bands in the beginning. The answer is 24.
