Question

you need to order three hinges for each of 15 doors. Each hinge costs $0.75. How much will the hinges cost? (Explain your answer)

Answer 1

$33.75

Explanation:

First, find the cost for each door. 3 hinges times $0.75 a hinge, that's $2.25 per door. Then, multiple that by 15, for each door. That comes out to $33.75.

Answer 2

your answer is 33.75. if each door has 3 hinges and there are 15 doors then you have 45 hinges, you then multiply 45 by .75 ( the cost of each hinge) and you get 33.75
