Number Consumed Total Utility 00 1 11 2 17 3 24 4 30 5 36 6 38 7 39 Based on the data in the table, you can conclude that the Multiple Choice marginal utility of the sixth unit is 2. total utility of 2 units is 16. total utility of 5 units is 88. marginal utility of the fourth unit is 96.

Take Jeremys total utility information in Exercise 6.1, and use the marginal utility approach to confirm the choice of phone minutes and round trips that maximize Jeremys utility.

Jeremy is deeply in love with Jasmine. Jasmine lives where cell phone coverage is poor, so he can either call her on the land-line phone for five cents per minute or he can drive to see her, at a round—trip cost of 2 in gasoline money. He has a total of 10 per week to spend on staying in touch. To make his preferred choice, Jeremy uses a handy utilimometer that measures his total utility from personal visits and from phone minutes. Using the values in Table 6.6, figure out the points 011 Jeremys consumption choice budget constraint (it may be helpful to do a sketch) and identify his utility-maximizing point.

Would you expect total utility to rise or fall with additional consumption of a good? Why?
