What is the efficient scale of the painting company

1. A restaurant currently has two cooks and ten waiters. Cooks earn $20 an hour and waiters earn $10 an hour. The last cook added 40 meals served to total output, while the last waiter added 20 meals served to total output. In order to maximize the number of meals served with a fixed budget, the manager should
a. should use more waiters and fewer cooks because productivity per dollar is higher for waiters than for cooks.
b. should use more waiters and fewer cooks because waiters are paid less than cooks.
c. should use more cooks and fewer waiters because cooks are more productive than waiters.
d. continue to use two cooks and ten waiters because cost is minimized for the given amount of output.

2. Suppose that you run a house-painting company and currently have 2 workers painting a total of 4 houses per month. If you hire a third worker, 6 houses can be painted per month. If you hire a fourth worker, 9 houses can be painted, and a fifth and sixth worker will increase the number of houses painted to 13 and 15, respectively. Diminishing returns
a. set in when the fourth worker is hired.
b. set in when the fifth worker is hired.
c. set in when the sixth worker is hired.
d. have not yet set in because output is still increasing

3. Use the following table to answer this question.

Demand is unit elastic when quantity demanded changes from
a. 10 to 9.
b. 9 to 8.
c. 8 to 7.
d. There is not enough information given to determine the correct answer.

4. Using the midpoint method, the price elasticity of demand for a good is computed to be approximately 0.75. Which of the following events is consistent with a 10 percent decrease in the quantity of the good demanded?

6. The market demand for a monopoly firm is estimated to be:
Qd = 100,000 - 500P +2M + 5,000PR
where Qd is is quantity demanded, P is price, M is income, and PR is the price of a related good. The manager has forecasted the values of M and PR will be $50,000 and $20, respectively, in 2012. The marginal cost function is estimated to be MC = 500 + 0.006Q. Total fixed cost in 2012 is expected to be $4 million.

d. $20.

7. The market demand for a monopoly firm is estimated to be:
Qd = 100,000 - 500P +2M + 5,000PR
where Qd is is quantity demanded, P is price, M is income, and PR is the price of a related good. The manager has forecasted the values of M and PR will be $50,000 and $20, respectively, in 2012. The marginal cost function is estimated to be MC = 500 + 0.006Q. Total fixed cost in 2012 is expected to be $4 million.

9. “Airlines” Scenario
An airline knows that there are two types of travelers: business travelers and vacationers. For a particular flight, there are 100 business travelers who will pay $600 for a ticket while there are 50 vacationers who will pay $300 for a ticket. There are 150 seats available on the plane. Suppose the cost to the airline of providing the flight is $20,000, which includes the cost of the pilots, flight attendants, fuel, etc.

a. $15,000
b. $40,000
c. $70,000
d. $25,000

10. Price discrimination
a. is an attempt by a monopoly to prevent some customers from purchasing its product by charging a high price.
b. forces monopolies to charge a lower price as a result of government regulation.
c. is an attempt by a monopoly to increases its profit by selling the same good to different customers at different prices.
d. increases the consumer surplus associated with a monopolistic market.

11. Suppose that you run a house-painting company and currently have 2 workers painting a total of 4 houses per month. If you hire a third worker, 6 houses can be painted per month.

18. While relaxing poolside one Sunday afternoon, Dickie was struck by a golf ball driven by Marty, a 14-year-old boy, who was playing the 9th hole at the Pike Creek Golf Club. The fairway for the 9th hole was 65 feet wide and 437 yards long, with a dog-leg in an easterly direction. Between the fairway and Dickie’s property was a “rough” containing brush and low lying trees. As Marty was approaching the green, he hit a towering shot which deflected off a tree, struck Dickie, bounced off his head and knocked a straw hat off of his girlfriend Patty’s head. Although the ball did not strike Patty herself, she became startled and fell from her beach chair, thus breaking her arm.
At trial plaintiff offered uncontested evidence that golf balls from the Club’s links regularly traversed onto his property two to three times a day. Which of the following statements is most accurate regarding the liability of the Pike Creek Golf Club/Marty for trespass?

A. Defendants are not liable, since they did not intentionally cause the golf ball(s) to traverse onto the plaintiff’s property.
B. Defendants would remain liable for the unpermitted intrusion of the golf ball(s) onto the plaintiff’s property.
C. Since the plaintiff should have reasonably anticipated that living next to a golf course would result in stray golf balls landing on his property, defendants would not be held liable.
D. Since the golf balls did not substantially interfere with the plaintiff’s use and enjoyment of his land, defendants would not be held liable.

19. Which of the following would be Dickie’s proper cause of action against Marty as a result of the golf ball hitting his head?
A. Assault but not battery
B. Battery but not assault
C. Assault and battery
D. Neither assault nor battery, since Marty did not intentionally cause Dickie to be struck

20. If Patty initiates a suit against Marty to recover damages for her broken arm, Patty will
A. recover for assault only
B. recover for battery only
C. recover for assault and battery
D. not recover
