Assume the demand curve faced by a monopolist is given by the following table:
price demand total revenue marginal revenue
55 45
60 40
65 35
70 30
75 25
80 20
85 15
90 10
95 5
100 0
(a) Fill in the columns of the table for total revenue and marginal revenue.
(b) Draw the demand curve and the marginal revenue curve.
(c) If the firm's marginal cost is $75, what is the equilibrium monopoly price? How much does a monopolist produce? (d) What would be the price and quantity produced if this were a competitive market (assume marginal costs to be $75)?
