Question 3 25 pts A firm produces good x using capital, K, and labor, L, as inputs in production. The firm's production and cost functions in the short-run are given below. TP or K L MPL Q TFC TVC TC AFC AVC ATC MC 16.5 8 700 16.5 9 706 16.5 10 708 PK=20, PL=10 A. Calculate the marginal product (of labor) (MPL), total fixed cost (TFC), total variable cost (TVC), total cost (TC), average fixed cost (AFC), average variable cost (AVC), average total cost (ATC), and marginal cost (MC) if the firm produces 706 units. (For MC, calculate TC first if the firm produces 700 units.) B. Based on the average total cost and marginal cost that you have calculated, is ATC increasing, decreasing, or at the minimum value in the short-run? In no more than one sentence, explain why. C. If the firm wants to minimize its total cost of production at 706 units of output level (in the long-run), what is the cost minimization condition to use in determining the combination of capital and labor? D. What should the marginal product of labor-to-marginal of product of capital ratio (MPL/MPK) be equal to so that profits are maximized at this level of output in the long-run
