In Exhibit I-4, if this firm is currently producing 20 units of output, this firma. is at its profit-maximizing pointb. could increase profits by increasing outputc. could increase profits by decreasing priced. should shut down28. At P = $24, Q = 200, MC = MR, AFC = $6, AVC = $25, the firm shoulda. increase output.b. decrease output.c. shut down.d. stay at the current output level, although profit = -$1,400.29. The firm?s supply curve isa. the same as the industry's supply curveb. the average total cost curvec. perfectly horizontald. the marginal cost curve above AVC30. At P = $24, AVC = $22 & ATC = $26, in the long run this firm shoulda. continue to operate at a lossb. earn a positive profitc. go out of businessd. increase output31.
