At her current level of consumption, Jess gets half as much marginal utility from an additional bagel as from an additional muffin. If the price of muffin is $2 each, then Jess is maximizing her utility if the price of a bagel is:

$1.00

Let MUc denote the marginal utility that Pablo receives from a cup of coffee, and let Pc denote the price of a cup of coffee. We typically expect that as Pablo buys more coffee:

MUc/Pc will fall.

Refer to the accompanying table. The total utility of consuming two dinners out per week is:

The total utility of one dinner is 100, and the marginal utility of the second dinner is 75, so the total utility of two dinners is 175.

Moe's reservation price for his economics textbook is $100. The week before the semester begins, Moe finds a copy of his textbook online for $75. Moe's consumer surplus from buying the textbook online is:

$25.

When Lorenzo eats 1 slice of pizza for lunch, his total utility is 23, and when he eats 2 slices of pizza for lunch, his total utility is 42. Assuming that Lorenzo's marginal utility from eating pizza is always positive, we can infer that his total utility from eating 3 slices of pizza at lunch is:

According to the law of diminishing marginal utility, the marginal utility of Lorenzo's third slice of pizza must be less than the marginal utility of his second slice. Since the marginal utility of his 2nd slice of pizza is 19, we know that the marginal utility of his third slice must be less than 19, implying that his total must be greater than 42 but less than 61 (= 42 + 19).

Suppose a cup of tea costs $0.60 and a scone costs $1.20. If Edith spends all of her income on these two goods, and at her current level of consumption, she receives a marginal utility of 6 utils from the last cup of tea she buys and a marginal utility of 24 utils from the last scone she buys, then Edith should:

buy less tea and more scones.

For Michael, the first cup of coffee he drinks every morning is heavenly. The second one is pretty good, but not as good as the first, and if he drinks a third cup he feels jittery and sick. For Michael, the marginal utility from drinking a cup of coffee is clearly:

decreasing

During Thanksgiving you participated in a pumpkin-pie eating contest. You really enjoyed the first two pies, the third one was okay, but as soon as you ate the fourth one you became ill and lost the contest. Your total utility ______ with the first three pies you ate.

Sven likes to water ski, but can only water ski during the one week each year when he is on vacation. Therefore, he plans to ski every day, for eight hours a day. The first day, Sven skied for eight hours and enjoyed every hour. The second day, Sven slept in and then skied for seven hours, which was fun but not as much fun as the first day. The third day, Sven skied for six hours, but was starting to get a bit bored by the end. The fourth day, Sven skied for four hours and then took a nap. On the fifth day of Sven's vacation, Sven went blueberry picking all day. Sven's total utility ______ with each hour that he skied.

increased

if Terry's total utility is maximized when he owns 10 pairs of shoes, then Terry's total utility from owning 7 pairs of shoes is ______ Terry's total utility from owning 8 pairs.

less than

Pat's total utility after eating 99 Reese's Peanut Butter Cups was greater than his total utility after eating 100 Reese's Peanut Butter Cups. Therefore, Pat's marginal utility from the 100th peanut butter cup was:

negative

Martha's current marginal utility from consuming orange juice is 60 utils per ounce and her marginal utility from consuming coffee is 50 utils per ounce. If orange juice costs $0.25 per ounce and coffee costs $0.20 per ounce, is Martha maximizing her total utility from the two beverages?

oj - 240 coffee- 250

Suppose that Cathy spends all of her income on 20 units of good X and 25 units of good Y. Cathy's marginal utility from the 20thunit of good X is 9 utils, and her marginal utility from the 25th unit of good Y is 19 utils. If the price of good X is $0.50 per unit and the price of good Y is $1.00 per unit, then to comply with the rational spending rule, Cathy should:

purchase less than 20 units of good X and more than 25 units of good Y.

Alex wants to maximize his utility. At his current level of consumption, Alex's marginal utility from an additional cup of coffee is 15 utils, and his marginal utility from an additional can of soda is 11 utils. If the price of a cup of coffee is $3 and the price of a can of soda is $2, Alex should:

reallocate his spending away from coffee and towards soda.

Joaquin's marginal utility from an additional slice of pumpkin pie is 4 utils and his marginal utility from an additional slice of pecan pie is 6 utils. If a slice of pumpkin pie costs $2.50, and a slice of pecan pie costs $3.00, then Joaquin:

should reallocate his spending towards pecan pie and away from pumpkin pie.

Consumer surplus measures:

the difference between the most a buyer would be willing to pay for a product and the price actually paid.

if the marginal utility of the 3rd cup of coffee is 23 and the marginal utility of the 4th cup is 15, then:

there is evidence of diminishing marginal utility.

If marginal utility is positive, then as consumption increases:

total utility will increase.
