    Finding Maximum Profit from Cost f(x)

    Greetings.

    C(q)= .25q^2+8q+25
    p(q)= 83-q

    I need help finding the maximum profit, and with what q value.

    For the profit function I have P(q)=-1.25q^2-75q-25

    To maximize profit I got -30. This is clearly wrong so any direction would be of great value.

    Thanks.

    For what do C, q, p, and P stand?

    Thank you!

    C = Cost
    p = Price
    P = Profit
    q = Quantity

    Sorry.
