Question 4 i. Discuss the difference between average revenue and marginal revenue. Why are both of these revenue measures important to a profit-maximizing firm? Discuss the law of diminishing returns and how it explains the shape of the short run average cost curve Camille's variable cost, VC, is his wage cost ($80 per worker per day) and his other input costs ($0.50 per cup). ii. iii. a. Complete the following table b. If the firm closes down and produces no output, what will be its total cost? Explain

QUESTION 2 When the article said that Bird was making 19% gross margin profit, this is O A. Accounting profit O B. Economic Profit O C. Neither accounting nor economic profit. D. Cannot tell from the article what kind of profit с

4. COST RELATIONSHIPS. A firm's total costs can be broken down into fixed costs (e.g., rent) and variable costs (e.g., payroll), so TC = FC + VC. Dividing by quantity converts these to averages, so TC/Q = FC/Q + VC/Q, or ATC = AFC + AVC. The additional cost incurred by producing one additional unit is the marginal cost, so MC = ATC/AQ, where the Greek letter delta (A) means "a change in." Here is a table showing the various costs for a simple firm that sells a product using a building (capital, a fixed input) and workers (labor, a variable input). Assume that the price of labor is 20 and the price of capital is 120. Use these three cost relationships to complete the table.
