a. The equations for total product, average product, and marginal product are:
TP = ___________________________
AP = ___________________________
MP = ___________________________
b. The estimated values of A and B are statistically significant at the (exact) levels, ________ and _________, respectively.
c. At _______ units of labor usage, marginal product of labor begins to diminish.
When the wage rate is $300, answer the following questions. (Remember that AP =

d. Average product of labor reaches its maximum value at ________ units of labor.
e. At the output for part d, average variable cost is $______________ and marginal cost is $____________.
f. When the rate of labor usage is 100 units of labor, output is _______ units.
Average variable cost is $_________ and marginal cost is $__________.
