A joint-cost function is defined implicitly by the equation c+ vc = 90 + 9A /9+g% where c denotes the total cost (in dollars) for producing ga units of product A and qg units of product B. (a) If qA = 4 and qB = 4, find the corresponding value of c. (b) Determine the marginal costs with respect to qa and qg when ga = 4 and qg = 4.
