Question : A firm has the following output and labor combinations, given 20 units of capital:
L 10 11 12 13 14
Q 48 55 61 65 67
a) Calculate the average product of labor and the marginal product of labor when L=11, 12, 13, and 14.
b) Suppose that capital costs $30 per unit (r = $30). What is the average fixed cost for each level of output?
c) Suppose that labor costs $40 per unit (w = $40). What is the average variable cost for each level of output?
d) Calculate the marginal cost for Q at levels of 55, 61, 65, and 67.
