Refer to Table 6.1, which shows the marginal utility of each additional unit of pretzel for a consumer. The first column of the table shows the number of pretzels consumed in
a day, and the second column of the table shows the marginal utility of each additional unit of pretzel. The total utility derived from the consumption of three pretzels is
units.

John likes Coca-Cola. After consuming one Coke, John has a total utility of 10 utils. After two Cokes, he has a total utility of 25 utils. After three Cokes, he has a total utility of 50 utils. Does John show diminishing marginal utility for Coke, or does he show increasing marginal utility for Coke? Supposethat John has $3 in his pocket. If Cokes cost $1 each and John is willing to spend one of his dollars on purchasing a first can of Coke, would he spend his second dollar on a Coke, too? What about the third dollar? If John’s marginal utility for Coke keeps on increasing no matter how many Cokes he drinks, would it be fair to say that he is addicted to Coke?

- Take Jeremys total utility information in Exercise 6.1, and use the marginal utility approach to confirm the choice of phone minutes and round trips that maximize Jeremys utility.arrow_forwardIf people do not have a complete mental picture of total utility for every level of consumption, how can they find their utility-maximizing consumption choice?arrow_forwardJeremy is deeply in love with Jasmine. Jasmine lives where cell phone coverage is poor, so he can either call her on the land-line phone for five cents per minute or he can drive to see her, at a round—trip cost of 2 in gasoline money. He has a total of 10 per week to spend on staying in touch. To make his preferred choice, Jeremy uses a handy utilimometer that measures his total utility from personal visits and from phone minutes. Using the values in Table 6.6, figure out the points 011 Jeremys consumption choice budget constraint (it may be helpful to do a sketch) and identify his utility-maximizing point.arrow_forward
- 8 of 15 Izzy who consumes only grilled chicken sandwiches and salads with low-fat dressing, has a weekly income of $50. She is currently consuming 5 grilled chicken sandwiches per week, at a price of $6 each, and 2 salads per week, at a price of $10 each. If the last sandwich and the last salad both added 15 units to Izzy's total utility: O A. She is making the utility-maximising choice OB. She should buy more salads and fewer sandwiches OC.

- Based on his preferences, Bill is willing to trade 3 movie tickets for 1 ticket to a basketball game. If movie tickets cost $6 each and a ticket to the basketball game costs $16, should Bill trade movie tickets for basketball tickets? Why or why not? Bill should O A. trade movie tickets for basketball tickets because his marginal utility per dollar spent on movie tickets is less than his marginal utility per dollar spent on basketball tickets. O B. trade movie tickets for basketball tickets because his marginal utility per dollar spent on movie tickets is greater than his marginal utility per dollar spent on basketball tickets. O C. trade movie tickets for basketball tickets because his marginal rate of substitution equals the ratio of the price of a basketball ticket to the price of a movie ticket. O D. not trade movie tickets for basketball tickets because his marginal rate of substitution is less than the ratio of the price of a basketball ticket to the price of a movie ticket.

O MU/P is consistently greater at all-you-can-eat restaurants. O Food at all-you-can-eat restaurants tends to have fewer calories, so consumers feel the need to consume greater volume of food. O People who eat at all-you-can-eat restaurants do not experience diminishing marginal utility. O Once the all-you-can-eat meal purchased, consumers view additional trips back to the buffet as having a price of zero. QUESTION 4 Total utility is best defined as the O additional satisfaction received from consuming one more unit of a product. O total satisfaction received from consuming a given amount of a product. O maximum amount of satisfaction from consuming a product. O change in marginal utility multiplied by the price of a product.arrow_forward
