    Rachel’s utility funtion U = x ∗ y, where MUx = y and MUy = x. The price of x is 2 and the price of y is unknown and equal to the variable py. Rachel’s budget constraint is 40 = 2 ∗ x + py ∗ y. When Rachel maximizes utility subject to her budget constraint, she purchases 5 units of y. What must be the price of y and the amount of x consumed? (Hint: solve for how...

    Suppose that a consumer’s utility function is U=xy with MUx=y and MUy=x. Suppose the consumer‘s income is $480. For this question you may need to use the following approximations: sqrt(2) is approximately 1.4, sqrt(3) is approx. 1.7 and sqrt(5) is approx 2.2. a) Initially, the price of y is $4 and the price of x is $6. What is the consumer’s optimal bundle? b) What is the consumer's initial utility? Now suppose that price of x increases to $8 and...

    Consider the utility function U(x,y) = 3x+y, with MUx=3 and MUy=1 e) On a graph with x on the horizontal axis and y on the vertical axis, draw a typical indifference curve (it is not exactly to scale, but it needs to reflect accurately whether there is a diminishing MRS x,y). Also, indicate on your graph whether the indifference curve will intersect either or both exes. label the curve U1. f) on the same graph draw a second indifference curve...
