Question : 61) Refer to Table 7-4. For steak and cheese and : 1245223

 

 

61) Refer to Table 7-4. For steak and cheese and grilled chicken sandwiches, the table contains the values of the marginal utility (MU) and marginal utility per dollar (MU/P) for Mabel Jarvis. Mabel has $14 to spend on steak and cheese and grilled chicken sandwiches. Which of the following statements is true?

A) If Mabel maximizes her utility she will buy three steak and cheese sandwiches and two grilled chicken sandwiches.

B) If Mabel was maximizing her utility when spending $14 and then received an additional $4, she would receive the most marginal utility per dollar if her next purchase was another grilled chicken sandwich.

C) Mabel will first buy two steak and cheese sandwiches; then with her remaining $6 she will buy three grilled chicken sandwiches.

D) To maximize her utility, Mabel will need a total of $36, the income needed to buy 6 steak and cheese sandwiches and 6 grilled chicken sandwiches.

 

62) The marginal utility per dollar that Harold Stratton receives from oranges is greater than the marginal utility per dollar Harold receives from pears. To maximize his utility, what should Harold do?

A) He should acquire more income so that he can afford to buy more oranges and pears.

B) He should reduce his consumption of both oranges and pears so that he can buy a greater variety of goods.

C) He should buy fewer pears and more oranges.

D) He should buy fewer oranges and more pears.

 

63) There are two conditions necessary for a consumer to maximize her utility. One is that the marginal utilities per dollar spent on each good and service consumed are equal. What is the other condition?

A) Total spending on all goods and services must equal the amount available to be spent.

B) The consumer must be satisfied with the choices she makes.

C) The total spent on each good and service is the same.

D) The prices of each good and service consumed must not be too high.

 

64) Marge buys 5 CDs and 7 DVDs. The marginal utility of the 5th CD and the marginal utility of the 7th DVD are both equal to 30 utils. Can we say that this is the optimal combination of CDs and DVDs for Marge?

A) No. We need to know her preferences for CDs and DVDs.

B) Yes.

C) No. We need to know the prices of the CDs and DVDs.

D) No. If this was the optimal combination, the marginal utility per dollar of the 5th CD and the 7th DVD would be equal.
