able below shows the marginal revenue and costs for a monopolist. Demand, Costs, and Revenues Price (dollars) Quantity Demanded Marginal Revenue (dollars) Marginal Cost (dollars) Average Total Cost (dollars) $76 100 $76 $25 $139.00 71 200 66 68 103.30 66 300 56 56 87.50 61 400 46 82 86.00 56 500 36 76 84.00 51 600 26 48 78.00 Instructions: Enter your answer as a whole number. If you are entering a negative number include a minus sign. a. What is the monopolist's profit-maximizing level of output

Answer 1

Answer:

The profit maximizing output for a monopolist is the output level where marginal cost is equal to marignal revenue.

Explanation:

Price  Q Demanded Marginal Revenue Marginal Cost

$76     100                 $76                         $25

71        200                  66                           68

66       300                  56                           56

61        400                  46                           82

56       500                  36                           76

51        600                  26                           48

Arranging the information in the chart above, we can see that for a quantity demanded of 300 units, and a price of $66, marginal revenue and marginal cost are exactly the same, $56.

Thus, the profit-maximizing level of output is 300 units.
