A consumer buys only two goods, X and Y.

a. If the MRS between X and Y is 4 and the marginal utility of X is 20, what is the marginal utility of Y?

b. If the MRS between X and Y is 3 and the marginal utility of Y is 6, what is the marginal utility of X?

c. If a consumer moves downward along an indifference curve, what happens to the marginal utilities of X and Y? What happens to MRS?
