If we graph Mary Granola's indifference curves with

avocados on the horizontal axis and grapefruits on the

vertical axis, then whenever she has more grapefruits

than avocados, the slope of her indifference curve is

22. Whenever she has more avocados than grapefruits,

the slope is 21/2. Mary would be indifferent between a

bundle with 14 avocados and 20 grapefruits and

another bundle that has 26 avocados and

a. 11 grapefruits.

b. 18 grapefruits.

c. 6 grapefruits.

d. 16 grapefruits.

e. 13.5 grapefruits
