time. For the 2,000th unit, marginal cost is equal to marginal revenue. The difference
between marginal revenue and marginal cost is greater for the first unit the firm
produces than the second, and greater for the second than the third, and so on.
Furthermore, marginal revenue is greater than marginal cost for every unit from the first
to the 1,999th. It follows that the
a. marginal cost curve for the firm has a downward-sloping portion and an
upward-sloping portion.
b. marginal cost curve for the firm is downward-sloping.
c. marginal cost curve for the firm is upward-sloping.
d. marginal revenue curve is downward-sloping.
e. c and d
The present value of $3,000 one year in the future at a 3.5 percent interest rate is
approximately
a. $4,045
