1.Assume that a consumer purchases a combination of products Y and Z and that the MU_y/P_y= 4 and MU_z/P_z= 6. To maximize utility, without spending more money, the consumer should

a. purchase less of Z and more of Y.

b. purchase more of Z and less of Y.

c. purchase more of both Y and Z.

d. make no change in the quantities Y and Z.

2.A consumer is making purchases of products Alpha and Beta such that the marginal utility of product Alpha is 63 and the marginal utility of product Beta is 40. The price of product Alpha is $9, and the price of product Beta is $5. The utility-maximizing rule suggests that, to stay within a given budget constraint, this consumer should

a. increase consumption of product Alpha and decrease consumption of product Beta.

b. increase consumption of product Beta and increase consumption of product Alpha.

c. increase consumption of product Beta and decrease consumption of product Alpha.

d. make no change in the consumption of Alpha or Beta.

a. 5A and 7B

b. 8A and 3B

c. 10A and 15B

d. 6A and 5B

4.The marginal utility of the last unit of apples consumed is 10, and the marginal utility of the last unit of bananas consumed is 8. What set of prices for apples and bananas, respectively, would be consistent with consumer equilibrium?

a. $4 and $5

b. $5 and $4

c. $8 and $10

d. $15 and $10

5.The first Pepsi yields Craig 14 units of utility and the second yields him an additional 10 units of utility. His total utility from threecans of Pepsi is 30 units of utility. The marginal utility of the third Pepsi is

a. 20 units of utility.
