Beyond the sound bites Current Events (after the Quiz):
Today is the Ch. 4 Sec. 1 Quiz.
Clear your desk except for a pencil. Once everyone is quiet, and no talking during the Quiz, we can begin. Be sure to put your name on the Quiz and the Scantron. You may write on both the Quiz and the Scantron.
If you finish early, you may take out non-class materials; once everyone is finished, put away the non-class materials. Then, I will collect the Scantron first, and then I will collect the Quiz.
Be sure your name is on both the Scantron and the Quiz.
If your name is not on the Quiz it will not be returned.

Chapter 5: Supply
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.
Reading Strategy
Complete the graphic organizer below by explaining how total revenue differs from marginal revenue. Then provide an example of each.
