Step 2. Look at Table 6.2. You can see from the fourth row/second column that three T-shirts are worth 63 utils.

Similarly, the second row/fifth column shows that two movies are worth 31 utils.

Step 3. From this information, you can calculate that point Q has a total utility of 94 (63 + 31).

Step 4. You can repeat the same calculations for each point on Table 6.3, in which the total utility numbers are

shown in the last column.

For José, the highest total utility for all possible combinations of goods occurs at point S, with a total utility of

103 from consuming one T-shirt and six movies.

Choosing with Marginal Utility

Most people approach their utility-maximizing combination of choices in a step-by-step way. This approach is

based on looking at the tradeoffs, measured in terms of marginal utility, of consuming less of one good and

more of another.

For example, say that José starts off thinking about spending all his money on T-shirts and choosing point P,
