Bruce buys 5 packs of crayons at $5 each, 10 books at $5 each, and 3 calculators at $5 each. If he has $200, how many bags can he buy with the change if one costs $10 each? Give me reasons, before answering the question
He pays 5 * 5 = $25 for buying crayons. He pays 10 * 5 = $50 for buying books. He pays 3 * 5 = $15 for buying calculators. The change he has for buying bags is 200 - 25 - 50 - 15 = $110. The number of bags he can buy is 110 / 10 = 11 bags. So the final answer is 11.
