$50,000. Ted earns $40,000, and Robin earns $60,000. Which of the following
statements is correct?

3) Rick buys a 1966 Mustang for $3,000, planning to restore and sell the car. He goes
on to spend $9,000 restoring the car. At this point he can sell the car for $10,000. As an
alternative, he can spend an additional $3,000 replacing the engine. With a new engine
the car would sell for $13,000. Rick should
a.complete the repairs and sell the car for $13,000.
b.sell the car now for $10,000.
c.never try such an expensive project again.
d.be indifferent between (i) selling the car now and (ii) replacing the engine and then
selling it.
4) From society's standpoint, cooperation among oligopolists is
a.desirable, because it leads to less conflict among firms and a wider variety of products
for consumers.
b.desirable, because it leads to an outcome closer to the competitive outcome than what
would be observed in the absence of cooperation.
c.undesirable, because it leads to output levels that are too low and prices that are too
high.
d.undesirable, because it leads to output levels that are too high and prices that are too
high.

c.both the short run and the long run.
d.neither the short run nor the long run.

spend money on advertising for products that have
a.superior quality.
b.inferior or mediocre quality.
c.low prices.
d.limited availability.
8) Suppose the point of tangency that characterizes long-run equilibrium for a
monopolistically competitive firm occurs at Q1units of output. This level of output, Q1,
a.exceeds the level of output at which marginal revenue equals marginal cost.
b.exceeds the level of output at which marginal cost equals average total cost.
c.falls short of the level of output at which price equals marginal cost.
d.exceeds the firm's efficient scale of output.
9) When motorcycles are taxed and sellers of motorcycles are required to pay the tax to
the government,
a.the quantity of motorcycles bought and sold in the market is reduced.
b.the price paid by buyers of motorcycles decreases.
c.the demand for motorcycles decreases.

receipts?

b.$2.5 billion

a.B+D.
b.C+F.
c.A+C+F+J.
d.B+C+D+F.

17) Scenario 10-4
The demand curve for fire extinguishers slopes downward and the supply curve for fire
extinguishers slopes upward. The production of the 500th fire extinguisher entails the
following:
♦ a private cost of $10;
♦ an external cost of $0;
♦ a private value of $9;
♦ an external benefit of $3.
In order to maximize the total benefit of fire extinguishers to society as a whole, should
the number of fire extinguishers produced be less than, equal to, or greater than 500?
Explain.
18) Figure 21-31
The figure shows two indifference curves and two budget constraints for a consumer
named Kevin.
Refer to Figure 21-31. If Kevin's income is $2,520 and point B is his optimum, then
what is the price of a shirt?

Martina offers two reasons for agreeing with Dean's decision. What are they?
