A monopolist faces a demand curve given by P = 20 Q and has total costs given by TC = Q2. By using a bit of calculus, you should be able to determine that the firm's marginal revenue is MR = 20 2Q and its marginal cost is MC = 2Q.

Now suppose that the country in which this monopolist is located decides to engage in international trade. The world price of the product produced by the monopolist is $12. The profit-maximizing output level is 6, and the profit-maximizing price equals $12. What are its monopoly profits at this price and quantity?
