output per day. The figure implies that the

225. Refer to Figure 18-5. Suppose one point on the firm’s production function is (L = 3, Q = 180),
where L = number of workers and Q = quantity of output. If the firm sells its output for $5 per

226. Refer to Figure 18-5. Assume that two points on the firm’s production function are (L = 2, Q =
180) and (L = 3, Q = 228), where L = number of workers and Q = quantity of output. The firm
pays its workers $120 per day. The firm’s non-labor costs are fixed, and they amount to $250
per day. We can conclude that
a. the firm sells its output for $12 per unit.
b. if the firm is currently employing 2 workers per day, then profit could be increased by $48 per
day if a third worker is hired.

to 228 units per day.
d. the firm’s maximum profit occurs when it hires 3 workers per day.
