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 would be the industry output level if this was aperfectly competitive industryinstead?
