Use the following information to answer the questions below.

 

The demand for tickets to the Meatloaf concert (Q) is given as follows:

 

                Q = 120,000 - 2,000P

 

The marginal revenue is given as:

 

                MR = 60 - .001Q

 

The stadium at which the concert is planned holds 60,000 people. The marginal cost of each additional concert goer is essentially zero up to 60,000 fans, but becomes infinite beyond that point.

8. Given the information above, what is the profit maximizing number of tickets sold and the price of tickets?

a)

0, $60

b)

20,000, $50

c)

40,000, $40

d)

60,000, $30

e)

80,000, $20

c)

When there are few firms in the market and the demand curve faced by each firm is highly elastic.
