Draw the indifference curve of the bundles (x,y) that are indifferent to bundle (x,y) = (11,2). It doesn't have to be drawn to scale (hand drawn is fine), but make sure to label any intercepts . b. Are these preferences monotonic? Explain? c. Are these preferences convex? Explain intuitively with a diagram.

Question

1. Let k = one plus the last digit of your student number. For example, if your student number is 1234567 then k=8. Suppose an individual as preferences over goods x and y that can be represented by the utility function:

U(x,y) = 120 / 1+ |x-ky|

where |x-ky| is the absolute value of x - ky (that's k times y)

a. Draw the indifference curve of the bundles (x,y) that are indifferent to bundle (x,y) = (11,2). It doesn't have to be drawn to scale (hand drawn is fine), but make sure to label any intercepts .

b. Are these preferences monotonic? Explain?

c. Are these preferences convex? Explain intuitively with a diagram.
