    marginal cost function

    The average cost of producing q units of a product is given by


    c


    = 880
    q
    +3600 e(3 q+4 )/830
    q
    . Find the marginal cost if q=100.
    Answer: The marginal cost is _______?_____ dollars/(one unit of the product).


    I know you have to get the derivative of the average cost function to find the marginal function, and then do you input 100 for q? i cant seem to get this answer right.......

    C = ((880/q) +3600) * (e^(3q+4/830)/q)
