Suppose a certain city has a monopoly cable-television company.This company has total costs TC = 2.5Q².This means MC = 5Q since MC is the derivative of TC with respect to output.

The demand in the community is of the form Q_d = 30 - P/10 (alternatively, the demand equation can be written as Q_d = 30 - 0.1P).

I need help graphically depicting the demand curve as well as the marginal cost (MC) curve.

If the cable company is free to choose its own price P_m and quantity Q_m, I need help graphically depicting the monopoly equilibrium price and quantity adding any other curves to the diagram that may be required to obtain the outcome.

I need help computing and stating the exact monopolist equilibrium price P_m and quantity Q_m that was depicted graphically.
