196.Maddy is currently using all of his income on milk at a price of $4 per unit and on fish at a price of $15 per unit. The marginal utility of the next unit of milk is 40 utils and the marginal utility of the next unit of fish is 100 utils. How can Maddy rearrange his consumption to increase his utility? (A) He could increase his milk consumption and decrease his fish consumption. (B) He should decrease his milk consumption and decrease his fish consumption. (C) He should increase his milk consumption and increase his fish consumption. (D) He should decrease his milk consumption and increase his fish consumption. (E) He should do nothing----his utility is already maximized

197.If a consumer is spending all of her income on two goods, X and Y, she maximizes her utility when (A) MUX MUY = PX PY (B) MUX + PX = MUY + PY (C) MUX /MUY = PY /PX (D) MUX = (E) MUX/PX = MUY/PY

198.Demand curves slope downward because _____________ slope downward. (A) Total utility curves (B) Marginal utility curves (C) Supply curves (D) Marginal cost curves (E) Production possibility curves

199.Which of the following statements are correct? I. The demand curve for good X slopes downward because marginal utility diminishes as more of good X is consumed. II. As the price of good X falls, the marginal utility of good X per dollar rises, prompting more consumption of good X. III. As the price of good X falls, the substitution effect prompts the consumer to consume more of good X. (A) I only (B) II only (C) I and II only (D) I and III only (E) I, II, and III

200.Julie is currently maximizing her utility by consuming a certain number of units of goods A and B. If the price of good B rises, she will ___________ her consumption of good A and ___________ her consumption of good B, until ___________. (A) Increase; decrease; the marginal utility per dollar is equal for both goods (B) Increase; decrease; the marginal utility per dollar is equal for both goods (C) Increase; decrease; the marginal utility per dollar per dollar is zero for both goods (D) Decrease; increase; the marginal utility per dollar is equal for both goods (E) Decrease; increase; the marginal utility per dollar is zero for both goods
