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

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
A) both goods until the marginal utility of the last CD purchased is four times the marginal utility of the last magazine purchased.

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 considerably different quantities of the two goods. Which of the following statements is true, given that 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.
D) the income and substitution effects offset each other but the price effect of an inferior good leads you to buy less corn.
