Answer 1

Answer:

b. the more wealth she has, the less utility she gets from an additional dollar of wealth.

Explanation:

Utility is the satisfaction derived from a good. Total Utility is the total satisfaction from all units of a good. Marginal Utility is the additional satisfaction from an additional unit of a good.

The Law of Diminishing Marginal Utility states that : As consumer gets more & more of a good, the additional utility (satisfaction) from each successive unit keeps on declining. It implies that marginal utility decreases, & total utility increases at a decreasing rate.

Therefore : A person has more marginal utility (additional satisfaction) from an additional dollar, if he has less money (dollars). And, relatively less marginal utility from an additional dollar if he has more money (dollars).

Example : A rich person having millions of dollars would get less marginal utility (additional satisfaction) from gaining a single dollar, than a poor person having few dollars.
