A)22 grapefruits.
B)24 grapefruits.
C)26 grapefruits.
D)28 grapefruits.
E)25 grapefruits.

Question

Quizplus · Accepted Answer

The slope of the indifference curve changes based on the relative quantity of avocados and grapefruits. When Mary has more grapefruits than avocados, the slope is steeper, and when she has more avocados than grapefruits, the slope is less steep. To maintain indifference between two bundles, the total utility derived from each must be the same. Given the specific slopes for different scenarios, the correct answer must balance the utility derived from each fruit type across the two bundles. Starting with a bundle of 24 avocados and 30 grapefruits, moving to 30 avocados means she must have fewer grapefruits to maintain the same level of utility. The correct answer, 24 grapefruits, reflects a balance that considers the changing slope of the indifference curve as the quantities of avocados and grapefruits change, maintaining her overall level of satisfaction.
