The following table shows the maximum amount five potential car buyers are willing to pay for each level of sales. Suppose that the cars are being sold by a car dealer operating as a monopoly (perhaps because there are no other car dealers in the market).

	Maximum Amount He or She Would Pay for the Car
Buyer 1	$40,000
Buyer 2	$35,000
Buyer 3	$30,000
Buyer 4	$25,000
Buyer 5	$20,000

a) If the price of the car is $30,000, the revenue will be how much?

b) If the marginal cost of each car is $20,000. The monopolistic car dealer will want to sell how many cars, and what will be the price?

c) In a perfectly competitive market, how many cars sold would be sold?

d) How does monopoly of supply affect price and quantity?
