2)
One reason that firms hire labor at the point where w = MPL is A)
B)
C)
D)

if w > MPL, the cost (w) of hiring additional workers is less than the benefits (MPL) of hiring them, so they should hire more workers.
if w < MPL, the cost (w) of hiring additional workers equals the benefits (MPL) of hiring them, so they have the right number of workers.
if w < MPL, the cost (w) of hiring additional workers exceeds the benefits (MPL) of hiring them, so they should hire fewer workers.
if w > MPL, the cost (w) of hiring additional workers exceeds the benefits (MPL) of hiring them, so they should hire fewer workers.

3)
