    Assume a monopolist with the following demand and cost relationships.
    Q = 400 - 20P
    TC = 10 + 5Q + Q^2 (Where "^" means "to the power of")

    Calculate the following:
    Profit maximizing price
    Profit maximizing quantity

    Demand curve:
    Q = 400 - 20P
    Rearranging:
    20P = 400 - Q
    P = 20 - 0.05Q

    Total Revenue:
    TR = PQ
    TR = (20 - 0.05Q)Q
    TR = 20Q - ...
