Provide an appropriate response.A manufacturer produces products A and B for which the average costs of production are constant at 3 and 5 (dollars per unit), respectively. The quantities qA, qB of A and B that can be sold each week are given by the joint-demand functions qA = 10 - pA + pB' and qB = 12 + pA - 3pB' where pA and pB are the prices (in dollars per unit) of A and B, respectively. Determine the prices of A and B at which the manufacturer can maximize profit.
