Suppose your income is 200, the price of good x is 2, and the price of good y is 3. You know that your utility function is U= 2(xy)^3.  (A) What amounts of x and y do you choose? (B) Can you generalize your choices to demand curves for x and y for any prices and income?

Let U(x, y) = 3x + y be the utility function of a consumer, whohas a budget of I. As a function of I, find the consumer’s Walrasian demand when the prices are px = py = 1. The price of good x increases to 2, find the new Walrasian demand for the new prices px = 2 and py = 1. Decompose this change into an income and a substitution effect.

Consider a market with two goods, x and z. The consumer’s utility function is U = x^0.2z^0.8 A. Derive the demand function for x and z. B. Let ? = 2, = 4 and = 50. Find the equilibrium quantities demanded of x and z.

Suppose your utility for goods x1 and x2 is represented by the following utility function:  U(x1,x2)= x11/5  x24/5 a) What is your marginal rate of substitution, MRS12? b)  If the price for good x1 is p1 = 2, the price for good x2 is p2 = 4, and your available income is m = 20, write down your budget constraint. c) Using the prices and income given at b) above, find your optimal consumption choice bundle (Marshallian demand) and its corresponding utility level. d) Illustrate your optimal consumption choice on a graph. e) For the prices given in b), what income would you need to achieve a utility level of 25?   PLEASE ONLY ANSWER PART C, D AND E
