Types of Profit; MR=MC John Scalise Mr. Gill 2B 1/25/11

Accounting Profits Accounting Profits is found when explicit costs are subtracted from the total revenue. Explicit costs are “monetary” items. For example, wages, rent and taxes. Accounting Profits = Total Revenue – Explicit Costs

Economic Profits Economic Profits is determined by subtracting total costs from total revenue. Total costs- are made up of explicit and implicit costs. Implicit costs are made up of opportunity costs. Economic Profits = Total Revenue – (explicit + implicit costs)

Profit Maximization The Profit Maximization point normally occurs at the point where the MR cost curve intersect the MC cost curve. (MR=MC)

Question 1 Which of the following best explains a marginal cost: A) the fixed cost of producing one more good B) the variable cost of producing one more good C) the average variable cost of producing one more good D) the average fixed cost of producing one more good E) the average total cost of producing one more good

Answer 1 The answer is B: the variable cost of producing one more good.

Question 2/3 Output Total Cost 0 $ ) The profit-maximizing level of output for this firm is (a)2 (b) 3 (c) 4 (d) 5 (e) impossible to determine from the information given 2) The marginal cost of producing the fourth unit of output is (a) $ 4 (b) $11 (c) $19 (d) $32 (e) impossible to determine from the information given

Answer 2/3 The answer to number 2 is A: $ 4. The answer to number 3 is E: impossible to determine from the information give.
