a. what is the marginal product of labor? the marginal product of capital?

mpl = $¬

mpk = $¬

b. what is the ratio of the marginal product of labor to the price of labor (mpl / pl )?

mpl / pl = ¬

what is the ratio of the marginal product of capital to the price of capital (mpk/ pk )?

mpk / pk = ¬

c. is the firm using the least-costly combination of inputs?
choose:
1. yes, because mpk/pk = mpl/pl.
-or-
2. no, because mpk/pk > mpl/pl.

d. does adding an additional worker or adding an additional tractor yield a larger increase in total revenue for each dollar spent?
choose:
1. revenue is increased more by spending money on an additional worker.
-or-
2. revenue is increased more by spending money on an additional tractor.
