Jeremy 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 roundâ€”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.
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.
26. Danny has $12 to spend on two goods: pies and soda. The price of a pie is $4, and the price of a can of soda is $2. To maximize his utility, Danny buys A) the combination that gives him equal total utility from pies and soda B) 2 pies and 2 cans of soda C) oniy sodas because they are iess expensive D) the combination that gives him the same marginai utility per doillar spent on pies as on soda

5. Max has $35 a day to spend on windsurfing and snorkeling and he can spend as much time as he likes doing them. The price of renting equipment for windsurfing is $10 an hour and for snorkeling is $5 an hour.

Calculate Max's marginal utility from snorkeling at each number of hours per day. Does Max's marginal utility from snorkeling obey the principle of diminishing marginal utility? Which does Max enjoy more: his 6th hour of windsurfing or his 6th hour of snorkeling?
Suppose the marginal utility for a $5 submarine sandwich is 100. In addition, the marginal utility for a $10 pizza is 250. Which of the following best explains what Jessica should do if she can afford to buy both but only wants one thing for dinner? O Buy the pizza, which has a higher marginal utility. Buy the pizza since the marginal utility per dollar spent is higher than that of the sub. Buy the submarine sandwich, which is cheaper. Buy the submarine sandwich since the marginal utility per dollar spent is less than that of the pizza.
Ari intends to purchase a new car and has narrowed it down to a Dodge Ram truck or a Toyota Camry. A Dodge Ram truck costs $55000 while a Toyota Camry costs $20000. The utility that Ari will get from Dodge Ram truck is 12500 while Toyota Camry will generate a utility of 2500. Note: A purchase generating utility tells us the marginal utility of the good. What is the Marginal Utility per Dollar for Dodge Ram truck? What is the Marginal Utility per Dollar for Toyota Camry? Will Ari be better off buying a Dodge Ram truck or a Toyota Camry? ODodge Ram truck OToyota Camry A
Currently, Paula is maximizing utility by purchasing five TV dinners (T) and four LeanCuisine Meals (L) each week. Suppose both T and L cost $5 each.a. Graph Paula’s initial utility-maximizing choice.b. Suppose the price of T falls by $1 and the price of L rises by $1.25. Can Paula stillafford to buy her initial consumption choices? What do you know about her new budgetconstraint?c. Make a new graph to show why Paula will choose to consume more T and less Lgiven her new budget constraint to maximize utility. Is her utility increased, decreased,or unchanged given the price change? [Hint: try to make the graph as big as possible tosee how the utility is tangent/intersects with the lines more easily] d. In part (b), suppose another scenario where the price of T rises by $1 and the priceof L falls by $1.25. Is Paula’s utility increased, decreased, or unchanged given the pricechange?

What is the maximum number of shoes that Sharon will consume?Explain ii.Assume that Mania has $1,200 per month to spend between dinners at aJapanese restaurant and evenings at Cru, a local bar. Assume that going to Crucosts $25 and eating at the restaurant costs $14.a. Draw Mania’s budget constraint with restaurants on the horizontal axis.b. Suppose Mania comes into some money and can now spend an extra$200 per month. Draw her new budget constraint. c. Suppose the price of restaurants decrease to $12, while her income andthe price of Cru is unchanged. Illustrate what happens to her budgetline.
The table shows Rita's total utility from burritos and hot dogs. When the price of a burrito is $4, Rita has $28 to spend, and the price of a hot dog falls from $4 to $2, how many burritos and hot dogs does Rita buy? What are two points on Rita's demand curve for burritos? When the price of a burrito is $4, Rita has $28 to spend, and the price of a hot dog is $4, Rita buys burritos and hot dogs. Everything else remaining the same, if the price of a burrito falls from $4 to $2, how many burritos and hot dogs does Rita buy? burritos and hot dogs. Rita buys So two points on Rita's demand curve for burritos are $2.00 each. burritos at $4.00 each and burritos at (...)
