Suppose a typical firm is producing $x$ units of output per day. Using any other plant size, the long-run average cost would increase. The firm is operating at a point at which a. its long-run average cost curve is at a minimum. b. its short-run average total cost curve is at a minimum. c. both (a) and (b) are true. d. neither (a) nor (b) is true.

A firm is producing at minimum average total cost with its current plant. Draw the firm's long-run average cost curve. Label it. Draw a point on the LRAC curve at which the firm cannot lower its average total cost. Draw the firm's short-run average total cost curve that is consistent with the point you have drawn. Label it. When the firm cannot lower its average total cost by changing its plant, then it is operating on its long-run average cost curve at a point with _______.
