Question

At a local print shop, 10 copies can be made for $4. At this rate, how much would it

cost to make 75 copies?

Answer 1

5 copies would cost $2.

70 copies would cost $28 and adding the $2 from the 5 copies would cost a total of $30.

Answer 2

Answer: $30 for 75 copies.

Explanation:

We will set up a proportion to help us solve. Let x be equal to the amount for 75 copies.

`\displaystyle (10 \ copies)/(\$4) = (75 \ copies)/(\$x)`

Cross-multiply:

10 * x = 75 * 4

10x = 300

Divide:

x = $30
