Thread: Finding the average cost?

    Finding the average cost?

    So here is the problem I am working on:

    Assume that C(x) represents the cost of producing x calculators. If C(100) = $500 and C'(100) = $4.75, what is the average cost of a calculator when producing 100 calculators?

    I was wondering how I should go about doing this? This is all the information I have from the math problem.

    Thank you in advance!

    What I know

    Well here is what I know:
    C(x) is the function that represents the cost for making x calculators.
    C(100) = 500 is the cost for making 100 calculators.
    C'(100) = 4.75, which is the derivative of the previous function, I believe is the profit for making each individual calculator.
    I believe that the next step would be to find the derivative of the derivative, but I was never given a function to work with.
