Alexus;

The $45 is a one time set up fee that is independent of the

number of tee shirts printed. After paying the $45 set up

fee, the rest of the cost is $15 times the number of shirts.

Your cost function as a function of the number

of Tee shirts printed is:

C(T) = 15T + 45

If we have $390 then

**390 = 15T + 45**

15T = 390-45

15T = 345

T = 345/15

**T = 23 shirts printed**
