Question 1

In spending all his income on beer and pizza, Fred finds that the marginal utility of the last pizza he consumed is 8, and the marginal utility of the last bottle of beer is 4. The price of a bottle of beer is $1.50. If Fred has maximized his utility, the price of pizza must be

Accepted Answer

To maximize utility, the consumer should allocate his budget in such a way that the marginal utility per dollar spent on each good is equal. The marginal utility of the last pizza is 8, and the marginal utility of the last beer is 4. Given the price of beer is $1.50, the marginal utility per dollar spent on beer is 4/$1.50 = 2.67. To have the marginal utility per dollar spent on pizza equal to this, we solve for the price of pizza: 8/Price of Pizza = 2.67, which gives Price of Pizza = $3.00.

Question 2

The table shows the marginal-utility schedules for goods A and B for a hypothetical consumer. The price of good A is $1, and the price of good B is $2. The income of the consumer is $8.  If the consumer spends the given budget and gets maximum utility out of it, then she is receiving how much satisfaction from each dollar spent on the final unit of good A consumed?

Question 3

Diminishing marginal utility explains why

Accepted Answer

Diminishing marginal utility explains why demand curves are downsloping, as it suggests that the more of a good or service a consumer has, the less they will want additional units, leading to a lower willingness to pay for more.

Question 6

The goal of a rational consumer is to maximize

Accepted Answer

The goal of a rational consumer is to maximize total utility from all goods consumed, as this reflects the overall satisfaction obtained from their consumption choices.

Question 7

Refer to the table and graph. Suppose that the price of X falls from $2 to $1, while the price of Y remains at $4. Which of the following represents the demand curve for X if the consumer has money income of $10 to spend on X and Y?

Accepted Answer

The answer of   Refer to the table and...

Question 8

A consumer's demand curve for a product is downsloping because

Accepted Answer

The law of diminishing marginal utility explains why the demand curve is downsloping; as more of a product is consumed, the additional satisfaction (marginal utility) gained from consuming one more unit decreases.

Question 9

Answer the question on the basis of the following marginal utility data for products X and Y. Assume that the prices of X and Y are $4 and $2, respectively, and that the consumer's income is $18.  What level of total utility will the utility-maximizing consumer realize?

Question 10

Assume that a consumer purchases a combination of products Y and Z and that the MU y/ Pᵧ = 30/2 and MU z/ P_z = 45/3. To maximize utility, without spending more money, the consumer should

Accepted Answer

The consumer is already maximizing utility because the marginal utility per dollar spent is equal for both products (15 for Y and 15 for Z).

Question 11

Assume that a consumer purchases a combination of products Y and Z and that the MU y/ Pᵧ = 25 and MU z/ P_z = 20. To maximize utility, without spending more money, the consumer should

Accepted Answer

To maximize utility without spending more money, the consumer should adjust their consumption to equalize the marginal utility per dollar spent on each good. Since MUy/Py is higher than MUz/Pz, the consumer should purchase more of Y and less of Z to equalize the marginal utility per dollar spent across both goods.

Question 12

The table shows the marginal-utility schedules for goods A and B for a hypothetical consumer. The price of good A is $1, and the price of good B is $2. The income of the consumer is $8.  If the price of B falls to $1, while the price of A and the consumer's income stay the same, what would be the utility-maximizing combination of goods A and B?

Question 14

Mr. Samuelson's current rates of purchase are such that the marginal utility of slacks is 18 and the marginal utility of ties for him is 5. If slacks and ties are priced at $12 and $2, respectively, it can be concluded that Mr. Samuelson

Accepted Answer

The principle of consumer equilibrium states that for a consumer to maximize satisfaction, the ratio of the marginal utility to the price of goods should be equal across all goods. Here, the marginal utility per dollar spent on slacks is 18/12 = 1.5, and for ties, it is 5/2 = 2.5. Since the marginal utility per dollar is higher for ties than for slacks, Mr. Samuelson is not maximizing his satisfaction and should spend more on ties and less on slacks.

Question 15

Betty is maximizing her satisfaction from spending her budget on two items, movie rentals and music downloads. If her marginal utility from the last movie rental is twice that from the last music download, what is the price of a movie rental if the price of a music download is $0.80?

Accepted Answer

According to the principle of utility maximization, consumers allocate their budget in a way that the last dollar spent on each good provides the same marginal utility. If the marginal utility from the last movie rental is twice that from the last music download, and the price of a music download is $0.80, then the price of a movie rental must be twice that, which is $1.60, to equalize the marginal utility per dollar spent on each.

Question 16

Assume that A and B are both priced at $1 per unit and that Mary has $10 to spend on A and B. She buys 6 units of A and 4 units of B. The marginal utility of the final unit of A bought is 12, and that of B is 8. This indicates that

Question 17

Answer the question on the basis of the following marginal utility data for products X and Y. Assume that the prices of X and Y are $4 and $2, respectively, and that the consumer's income is $18.  If the price of X decreases to $2, then the utility-maximizing combination of the two products is

Question 18

Sharon purchases two products with a given fixed budget, orange juice and soda. Her marginal utility from orange juice is 60, and her marginal utility from soda is 30. The price of a bottle of orange juice is $2.00, and the price of soda is $1.00. These data suggest that

Accepted Answer

The marginal utility per dollar spent on orange juice (60/2 = 30) is equal to the marginal utility per dollar spent on soda (30/1 = 30), indicating that Sharon is maximizing her utility given her budget.

Question 19

What do the income effect, the substitution effect, and diminishing marginal utility have in common?

Accepted Answer

These concepts all contribute to explaining why demand curves typically slope downwards, indicating that as the price of a product decreases, consumers are more likely to purchase more of it. The income effect suggests that a lower price increases the purchasing power of consumers, allowing them to buy more. The substitution effect indicates that as the price of a product decreases, it becomes relatively cheaper compared to substitutes, leading consumers to switch their purchases to the cheaper option. Diminishing marginal utility explains that the more of a good consumers have, the less additional utility (satisfaction) they get from consuming more, which influences how much they're willing to pay for additional units, contributing to a downward-sloping demand curve.

Question 20

In 2015, the federal government started requiring restaurants to print calorie counts next to menu items. The intent was to persuade consumers to

Accepted Answer

The federal government's requirement for restaurants to print calorie counts next to menu items in 2015 was aimed at helping consumers make more informed choices about their food consumption, with the intent of controlling and reducing their total calorie intake. This initiative was part of broader public health efforts to address obesity and encourage healthier eating habits.
