To find the total cost for an order of 20 copies, we can substitute x = 20 into the function:
c(20) = 11.00 + 0.20 * 20
c(20) = 11.00 + 4.00
c(20) = 15.00
Therefore, the total cost for an order of 20 copies would be $15.00.
A printing service charges is set up fee of $11.00 for each order and 20 cents more for each copy. the total cost c in dollar for an order of x copies is given by the following function c ( x) = 11.00 + 0.20 x what is the total cost for in order of 20 copies
