5) Consumers maximize total utility within their budget constraint by buying

B) whatever they like the best. D) the goods with the largest total utility per price ratio.

6) If a consumer always buys goods rationally, then

7) Carolyn spends her income on popular magazines and music CDs. If the price of a CD is four times
the price of a magazine and if Carolyn is maximizing her utility, she buys

8) Aisha and Debbie both purchase milk and bread at the same Quik Mart. They have different tastes for
milk and bread and different incomes. They both buy some milk and some bread, but they buy

Aisha and Debbie are utility-maximizers?
A) In equilibrium, the marginal utility per dollar ratio of milk equals to that of bread for each individual.
B) In equilibrium, the marginal utility per dollar ratio of milk for Aisha must be equal to the marginal
utility per dollar ratio of milk for Debbie, and the marginal utility per dollar ratio of bread for Aisha must
also be equal to the marginal utility per dollar ratio of bread for Debbie.
C) In equilibrium, if the marginal utility per dollar ratio of milk for Aisha is greater than the marginal
utility per dollar ratio of milk for Debbie, then the marginal utility per dollar ratio of bread for Aisha must
be smaller than the marginal utility per dollar ratio of bread for Debbie.
D) No statement can be made about their respective marginal utility per dollar ratios for Aisha or Debbie
without knowing the exact prices of each good.

9) The demand curve for corn is downward sloping. If the price of corn, an inferior good, falls,
A) the income effect which causes you to reduce your corn purchases is smaller than the substitution
effect which causes you to increase your corn purchases, resulting in a net increase in quantity demanded.
B) the income effect which causes you to increase your corn purchases is larger than the substitution
effect which causes you to reduce your corn purchases, resulting in a net increase in quantity demanded.
C) both the income and substitution effects reinforce each other to increase the quantity demanded.
