Figure 18-2.The figure shows a particular firm's value-of-marginal-product (VMP) curve.On the horizontal axis,L represents the number of workers.The time frame is daily.   -Refer to Figure 18-2.Assume the following: • 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. C)  the marginal cost per unit of output is $2.50 when output is increased from 180 units per day to 228 units per day. D)  the firm's maximum profit occurs when it hires 3 workers per day. -Refer to Figure 18-2.Assume the following: • 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.
