Aprinting service charges a set-up fee of $9.50 for each order and 20 cents more for each copy. the total cost, c (in dollars), for an order of x copies.

what is the total cost for an order of 40 copies?

17.5

Step-by-step explanation:

9.5+20*40

$17.50

Step-by-step explanation:

This problem can be written as a function C(x), the cost for "x" number of copies.

The constant, or flat fee, is $9.50 because this cost will always be there no matter how many copies you order.

The rate is 20 cents, or 0.20 for every "x".

Write this as a function:

C(x) = 0.20x + 9.50

To find the cost of an order of 40 copies, substitute x for 40 in the function.

C(x) = 0.20x + 9.50

C(40) = 0.20(40) + 9.50

C(40) = 8 + 9.50

C(40) = 17.50

*Remember to always write money with two decimals.

The cost is $17.50.
