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.
