A monopolist sells in two markets. The demand curve for her product is given by p1 =119-2x1 in the first market and p2 = 123-5x2 in the second market, where xi is the quantity sold in Market i and pi is the price charged in Market i. She has a constant marginal cost of production, c = 3; and no fixed costs. She can charge different prices in the two markets. What is the profit-maximizing combination of quantities for this monopolist?
