The law of diminishing marginal utility says that:. a. as a person consumes more and more of a certain good, the addition to total satisfaction decreases.
b. as a person's income increases, the satisfaction associated with each dollar spent decreases. as
c. a person consumes more and more of a certain good, the additional satisfaction increases.
d. as a person's income increases, the satisfaction associated with each additional dollar earned increases.
Assume that this law holds for Quincy with ice cream and pretzels. Quincy decides to eat less ice cream and more pretzels. As a result:.
A. Quincy's marginal utility of ice cream decreases, and his marginal utility of pretzels increases.
B. Quincy's marginal utility of both ice cream and pretzels decreases.
C. Quincy's marginal utility of both ice cream and pretzels increases.
D. Quincy's marginal utility of ice cream increases, and his marginal utility of pretzels decreases.

1. a. As a person consumes more and more of a certain good, the addition to total satisfaction decrease.

2. D.Quincy's marginal utility for ice cream increases and his marginal utility for pretzels decreases.

Explanation:

Diminishing marginal utility implies that one gains extra satisfaction from the consumption of an extra unit of a particular good but that as one continue to consume, there'll be dissatisfaction because the extra unit consumed will not bring more satisfaction like the former ones.

For example, if one is thirsty and buys water, an extra unit will at first give satisfaction but more extra water will not be as satisfying like the first one.

If Quincy eats less ice cream and more pritzels, the marginal utility for ice cream will increase as she'll get more satisfaction because she only consumed less while for pritzels, the satisfaction will reduce if she takes an extra.
