6) Table 18-9
The following table shows the production function for a particular business. The

sells, and the manager pays each worker $80 per day. Assuming no changes in either the

10) Sonny's Surfer Shop produces and sells custom surf boards. Assume that labor is
the only input that varies for the firm. The firm's owner has determined that if she hires
10 workers, the firm can produce 10 surf boards per day. If she hires 11 workers, the
firm can produce 12 surfboards per day. The firm sells each surfboard for $2,000, and it
pays each of its workers $200 per day. Which of the following is correct?
a.For the 11th worker, the value of the marginal product of labor is $400.
b.For the 11th worker, the value of the marginal product of labor is $4,000.
c.The firm should not hire the 11th worker since hiring this worker reduces profit.
d.In order to justify hiring the 11th worker the firm will need to raise the price of a
surfboard.

a.$60.
b.$45.
c.$30.
d.$15.
12) Scenario 15-8
Mega Media Cable TV is able to purchase an exclusive right to sell a premium sports
channel in its market area. Let's assume that Mega Media pays $100,000 a year for the
exclusive marketing rights to the sports channel. Since Mega Media has already
installed cable to all of the homes in its market area, the marginal cost of delivering the
sports channel to subscribers is zero. The manager of Mega Media needs to know what
price to charge for the sports channel service to maximize her profit. Before setting
price, she hires an economist to estimate demand for the sports channel. The economist
discovers that there are two types of subscribers who value premium sporting channels.
First are the 3,000 die-hard sports fans who will pay as much as $150 a year for the new
channel. Second, the premium sports channel will appeal to 20,000 occasional sports
viewers who will pay as much as $25 a year for a subscription to it.
If Mega Media Cable TV is able to price discriminate, what would be the maximum
amount of profit it could generate?
a. $950,000
b. $850,000
c. $400,000
d. $350,000
