The problem tells you flat out what to do: just plug in 75 in place of P. It couldn't be simpler. If you're smart enough to be able to copy and paste your homework on this forum, you can certainly punch numbers into a calculator to solve for C(75).

What happens to the cost if you plug in 100 for P?
