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.
Answer:
The correct answer is letter "D": the output effect works to increase total revenue and the price effect works to decrease total revenue.
Explanation:
The output effect in a monopoly takes place when the price of input will raise the production costs of a business and reduce its output level and vice-versa. The price effect refers to the impact an activity has on the value of something. The price effect consists of the effect of substitution and the effect of profits. While the output effect has the purpose of increasing revenue, the price effect works towards decreasing it.

The CAPM model or Capital Asset Pricing Model indicates the relationship between the amount of risk and the expected profit for a certain investment. This model holds many assumptions, which from the ones provided we can say that assumptions I, II, and III are all correct and part of this model. The only assumption that is not correct is IV, since the level of risk aversion that each investor has depends on how much they know about their investment.
