The demand function of a monopoly?

A monopoly firm has the following demand function:

Q = 100 – 0.2P, where Q is the quantity of output sold per month and P is the price per unit. A firm’s short run total cost function per month is: STC = 50 + 20Q + Q2

Based on the above information, you are required to calculate each of the following:

1 Marginal Revenue function (4)

2 Marginal Cost function (4)

3 Profit maximizing price (4)

4 Profit maximizing output (4)

5 Total profit (4)

Update:

A little explanation of each of the concepts and how they are calculated will be useful. Also, some web or other resources will be appreciated.

    1. Q=100-0.2P,or P=500-5Q

    PQ=500Q-5Q*2

    MR=dPQ/dQ=500-10Q

    2.MC=dSTC/dQ=20+2Q

    3. MC=MR,500-10Q=20+2Q

    Q=480/12=40

    P=500-200=300

    4. Q=40=100-60

    5.PQ=TR=20,000-3,200=16,800

    STC=50+800+1,600=2,450

    Profit=16,800-2,450=14,350
