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 = 2000 - Q where 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.

What is the equilibrium output level produced by the profit-maximizing monopoly firm in this industry?
