Suppose Declan likes to eat Grapefruits and Avocados. We graph his indifference curve with grapefruit on the vertical axis and avocados on the horizontal axis. Whenever he has more grapefruit than avocados, the slope of his indifference curve is3/2. whenever the opposite is true, the slope of his indifference curve is1. Declan would be indifferent between a bundle with21avocados and67/2 grapefruits and another bundle with 31avocados and :

(a) 8 grapefruits

(b) 21 grapefruits

(c) 10 grapefruits

(d) 14 grapefruits

(e) 18 grapefruits
