Revenue/Profit Maximizing

[viperx116]

I don't know if this is the right place to post but here goes:

Problem:
Total Cost = 120+2Q+.05Q^2
Annual demand is P = 10-0.05Q

1. Calculate the revenue maximizing of the quantity level (Q) and the price level (P).

2. Calculate the profit maximizing of the quantity level (Q) and the price level (P).

The "Annual Demand" line is mysterious. What does that mean?

Perhaps Q*P is the Revenue? Can you maximize: R(Q) = Q*P = 10Q - 0.05Q^2?
