Question

A printing service charges a set-up fee of $14.50 for each order and 15 cents more for each copy. The total cost, C (in dollars), for an order of x copies is given by the following function.

C (x) = 0.15x + 14.50
What is the total cost for an order of 30 copies?

Answer 1

Answer: $19

Explanation:

Since we want 30 copies, let x=30.

`C(30)=0.15(30)+14.50=19`
