“time.” How much time? Time to do what?
4. Define: total product, marginal product, average product
5. Explain the “law of diminishing marginal returns.”
6. Look at the graph on p. 203. When does total product begin to decrease? When does

- Do the quick quiz on 207 and check answers.
- Explain IN YOUR OWN WORDS why the marginal cost curve intersects the AVC and

your head around this if you don’t get it at first.
