3) Table 17-5
The information in the table below shows the total demand for premium-channel digital
cable TV subscriptions in a small urban market. Assume that each digital cable TV
operator pays a fixed cost of $200,000 (per year) to provide premium digital channels in
the market area and that the marginal cost of providing the premium channel service to
a household is zero.
Refer to Table 17-5. Assume there are two profit-maximizing digital cable TV
companies operating in this market. Further assume that they are able to collude on the
quantity of subscriptions that will be sold and on the price that will be charged for
subscriptions. How much profit will each company earn?
a. $610,000
b. $550,000
c. $405,000
d. $205,000
4) Suppose that a firm operating in perfectly competitive market sells 300 units of
output at a price of $3 each. Which of the following statements is correct?

6) Figure 14-1
Suppose that a firm in a competitive market has the following cost curves:
If the market price is $6.30, the firm will earn
a.positive economic profits in the short run.

d.zero economic profits in the short run.
7) Table 18-11
Consider the following daily production data for MadeFromScratch, Inc.
MadeFromScratch sells cupcakes for $2 each and pays the workers a wage of $325 per
day.
Refer to Table 18-11. Suppose that the firm suffers a loss of some of their technology
such as the theft of their industrial mixers. After the theft, MadeFromScratch employees
produce fewer cupcakes than they could before because they must mix the cupcake
batter by hand rather than using the high-speed mixers. Because of this change, the
firm's
a.demand for labor shifts right.
b.demand for labor shifts left.
c.supply of labor shifts right.
d.supply of labor shifts left.
