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?
Use reasoning to answer the following question.
11
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.

The answer is 11
