x = 1 - p + 2q, y = 11 + P - 3q, Q = 4x + y. Solve the problem in the two ways suggested under Example 6-12. The demand functions for two complementary goods are x = 11 - 2p - 2q, y = 16 - 2p - 3q. The joint-cost function is Q = 3x + y. The demand functions are p = 20 - 2x - y, q = 12 -x - y, and the joint-cost function is Q = x^2 + 2y^2. x = 1 - p + 2q, y = 11 + P - 3q, Q = 4x + y.
