Question: 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?
Answer:
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.
