The following table depicts the daily output price and costs
The following table depicts the daily output, price, and costs of a monopoly dry cleaner located near the campus of a remote college town. (See page 540.) Output (suits cleaned) Price per Suit ($) Total Costs ($) 0 8.00 3.00 1 7.50 6.00 2 7 .00 8.50 3 6.50 10.50 4 6.00 11.50 5 5.50 13.50 6 5.00 16.00 7 4.50 19.00 8 4.00 24.00 1.Compute revenues and profits at each output rate. 2.What is the profit-maximizing rate of output? 3.Calculate the dry cleaner’s marginal revenue and marginal cost at each output level. What is the profit-maximizing level of output
Solution
Answer:
Profit Maximization: The monopolist\'s profit maximizing level of output is found by equating its marginal revenue with its marginal cost, which is the same profit maximizing condition that a perfectly competitive firm uses to determine its equilibrium level of output.

To calculate the Dry cleaner’s Profits, TR, MR, & MC at each output rate:
Formulae:
TR = Q X P
Profit = TR – TC
MR = TR/ Q
MC = TC/ Q

The profit-maximizing level of output:
Both 5 suits and 6 suits generate the same profit ($14.00) however 5 generates a higher rate of profit than 6 because it generates the same dollar profit on lower sales.
