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

Since x denotes the number of copies, then we must substitute x=50 into the given equation, that is,
[tex]C(50)=0.05(50)+14.75[/tex]which gives
[tex]C(50)=17.25[/tex]then, the answer is $17.25 dollars.
