Errata for Chapter 5

1. Replace the existing versions of Exhibits 5-3, 5-4, and 5-5 with the new Exhibit 5-3, the new Exhibit 5-4 and the new Exhibit 5-5.

2. Replace the second paragraph on page 161 with the following:

For a concrete example, suppose it takes a yard of fabric to make a dress, and the cost of fabric goes up by 3 dollars a yard. That adds $3 to the variable cost of making 1 dress, it adds $6 to the variable cost of making 2 dresses, and so forth.
