Question

If we graph Mary Granola's indierence 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 indierence curve is -2. Whenever she has more avocados than grapefruits, the slope is -1=2. Mary would be indifferent between a bundle with 11 avocados and 23 grapefruits and another

bundle that has 19 avocados and: ( please show work or explain. i already know the answer, just need to know how to get it)

(a) 15 grapefruits.

(b) 19 grapefruits.

(c) 11 grapefruits.

(d) 13 grapefruits.

(e) 14 grapefruits.

Explanation / Answer

X = avocados

y = grapefruits

So when she has more grapefruits than avocados, the slope of her indierence curve is -2 hence at that time

u(x,y) = 2x+y = 2* 11+ 23 = 45

Now In second case:

U(x,y) = x+2y = > 45 = 19 + 2*y = > y = 13 [d] answer
