A7 Suppose a monopolist sells a product to two consumers i = 1,2 with linear inverse demand functions p1 = 26 - 2x1 and p2 = 23 - 4x2, where xi and pi are the quantity demanded and the price per unit paid by consumer i, respectively. The monopolist has a constant marginal cost equal to 2. Determine the profit-maximising solution to the second-degree price discrimination problem, where the monopoly offers take-it or leave-it contracts of quantity xi for a total price 06 of r; (i = 1, 2) that each consumer will self-select. What consumer surplus does consumer 1 obtain from purchasing and consuming each package
