Reference the following information about the market demand function for questions 1 to 15. These questions are on different types of market structures - monopoly, perfect competition, Cournot oligopoly market, and the Stackelberg oligopoly market.

The market demand function is given the following equation:P = 4000 - Qwhere Q is the industry's output level.

Suppose, initially, this market is served by a single firm.

Let the total cost function of this firm be given the function C(Q) = 200Q. The firm's marginal cost of production (MC) is equal to the firm's average cost (AC):MC = AC = 200.

1. What is theoutput levelproduced by the profit-maximizing firm in this industry?

2. What will be themarket pricecharged by the monopolist at the profit-maximizing level of output?

3, What will be theprofitearned by the monopolist at the profit-maximizing level of output?
