4 units.
b.
5 units.
c.
6 units.

is minimized.
28.
Refer to Table 14-8. In order to maximize profits, the firm will produce
a.
1 unit of output because marginal cost is minimized.

4 units of output because marginal revenue exceeds marginal cost.
c.
5 units of output because marginal revenue equals marginal cost.
d.
7 units of output because total revenue is maximized.
