Kevin received 80 total units of utility from the first four chips he consumed. If the marginal utilities of the first, second, and third chips are 20, 25, and 20, respectively, the marginal utility of the fourth chip is: |

| | B) | 20 units of utility |
| | C) | 15 units of utility |
| | D) | unknown, since Kevin's utility does not conform to the usual rules |

| | B) | Josh could increase his utility by consuming relatively more oranges |
| | C) | Josh is maximizing his utility at his current consumption levels |
| | D) | More information is required to determine if Josh should change his consumption of apples and oranges |
