            Suppose a monopolist sells its good to three people. Each person
can only purchase one good. The first person is willing to pay $20
for the good, the second person is willing to pay $18, and the
third is willing to pay $16. These three people make up the entire
market for this monopolist. If the firm can perfectly
price discriminate, how much revenue can it earn from selling 3
units?
Which of the following is true of the relationship between price
and marginal cost under monopolistic competition?
 | 
P = MC at all levels of output | 
 | 
P = MC only at the profit-maximizing quantity | 
 | 
P > MC at the profit-maximizing quantity | 
 | 
P < MC at the profit-maximizing quantity | 
 | 
P < MC at the quantities below the profit-maximizing
quantity |
