ESSAY
1.Give some examples of opportunity cost.
ANS:
A prime example is the income students forgo by not working full time while they are attending college. Another example is the interest income a person must forgo if she or he pays cash for an automobile.

2.Compare a football quarterback’s daily and yearly completed pass percentage to a business’s marginal and average product.
ANS:
Just as a quarterback’s daily (marginal) average affects his yearly average, so too does the marginal product of a firm affect its average product. If at midseason, for example, a quarterback is completing 30 percent of his passes and for the day he goes 10 for 20 (that is, he completes 50 percent), his yearly average will rise slightly. If he goes 5 for 25 (25 percent) for the day, his yearly average will fall slightly.

3.Why is the relationship between marginal product and marginal cost an inverse one?
ANS:
Inputs may cost a given amount. The cost of an input is spread over the amount of the marginal product. Therefore, when marginal product is rising, the marginal cost decreases. And when marginal product is falling, the marginal cost increases.

4.Draw two graphs: one showing the relationship of average product, marginal product, and total product; the other showing the relationship of AFC, AVC, and ATC. Then relate the shape of the marginal product to that of the marginal cost.
ANS:
Students can draw these graphs by using Figures 5-1 and 5-2 as references, if necessary. Students should observe that as the marginal product rises, the marginal cost declines; and as the marginal product declines, the marginal cost rises. A similar relationship holds with average product and average variable cost.
