In-class assignment (you may work with a partner):

Directions: Explaining

Complete the graphic organizer by explaining how marginal product changes in each of the three stages of production.


Section 3: Cost, Revenue, and Profit Maximization

Cost and revenue are added to the theory of production. Several important measures of cost are introduced, including fixed cost, variable cost, total cost, and marginal cost. Total revenue and marginal revenue are the most important measures of revenue. The firm reaches the break-even point when the revenue from sales is large enough to cover the total cost of production. Furthermore, the firm finds its profit-maximizing quantity of output where the marginal cost of production is exactly equal to marginal revenue from the sale of the product.
