(86) Economies of scale are illustrated by
U. (87) When output is 100 units, the firm’s total fixed cost is \$500. What will this firm’s total fixed cost be if output doubles to 200 units?
(88) When Super Stuff Corporation produces 5,000 units, total costs equal \$150,000 and total variable costs equal \$75,000. At this level of output, what is Super Stuff’s average fixed cost?
(89) The MC Curve always intersects the AVC curve a. at the maximum of the AVC b. at the minimum of the AVC c. at the origin d. it does not intersect the AVC at all
