Maximizing Profits The weekly demand for DVDS manufactured by a certain media corporation is given by p = -0.0003x? + 70 where p denotes the unit price in dollars and x denotes the quantity demanded. The weekly total cost function associated with producing these discs is given by C(x) = -0.002x2 + 16x + 3000 where C(x) denotes the total cost (in dollars) incurred in pressing x discs. Find the production level that will yield a maximum profit for the manufacturer. Hint: Use the quadratic formula. (Round your answer to the nearest integer.) X = DVDS
