Consider the table below, which provides information about the marginal utility ice cream and coffee for a consumer. The price of ice cream is $2, and the price of coffee is$1. Answer the following questions based on the information in this table.

Quantity MU (ice cream) MU/P (ice cream) MU (coffee) MU/P (coffee)
1 20 12
2 18 10
3 16 8
4 14 6
5 12 4
6 10 2
7 8 1
Table 6.13
1. Calculate and fill in the information for MU/P for both ice cream and coffee.
2. Suppose this consumer has $9 and spends$6 on ice cream (three cones) and $3 on coffee (three cups). Are they maximizing their utility? If so, explain why. If not, explain how they can adjust their consumption decisions to maximize their utility. 3. Suppose instead that this consumer spends their$9 on two ice cream cones and five cups of coffee. Are they maximizing their utility? If so, explain why. If not, explain how they can adjust their consumption decisions to maximize their utility.
4. Why does the marginal utility of consuming ice cream and coffee decline as more are consumed? What principle or law explains this process?
