Document Summary

P= price per unit of the good. Shows the total amount of money gained by a producer by selling a certain amount of a good. Ex: a grocery store sells 2000 pounds of apples at . 00 per pound. Total revenue: 2000 pounds . 00 per pound = . Is equivalent to price per unit of good. The revenue gained by the producer by selling one more unit of good. Ex: if a painter sold his 10th painting for . Mr of the 10th painting is 500. How the price is determined in a perfectly competitive firm. The price is determined by the equilibrium point in which the demand curve and the supply curve intersect in the perfectly competitive market. The firm/business follow that price to get the highest profit. Profit= total revenue (tr) - total cost (tc) Profit measures the total amount that a business gain by selling and producing a certain product.

If the monopolist sells 8 units of its product, how much totalrevenue will it receive from the sale?

You wil have to complete the entries in this table to get ananswer. It is a wothwhile exercise and I encourage you to completethe table.

HINT: (a.) Total Revenue = Price x Quantity. (So for quantity of 3x price of $29 = 87 total revenue)

(b) Average Revenue is the same as Price. (So column 2 and column 4would be the same. Calculate to see if that is correct)

(c) Marginal Revenue = Change in TR divided by change in quantity.(You calculated TR = 87 for Q=3. Thus to find MR for Q = 3, findthe change in TR= 87 - 64 and divided by one).

A) 112
B) It cannot be determined from the information provided.
C) 164
D) 40
