5.2 David gets $3 per week as an allowance to spend any way he pleases. Because he likes only peanut butter and jelly sand- wiches, he spends the entire amount on peanut butter (at $0.05 per ounce) and jelly (at $0.10 per ounce). Bread is pro- vided free of charge by a concerned neighbor. David is a par- ticular eater and makes his sandwiches with exactly 1 ounce of jelly and 2 ounces of peanut butter. He is set in his ways and will never change these proportions. a. How much peanut butter and jelly will David buy with his $3 allowance in a week? b. Suppose the price of jelly were to increase to $0.15 an ounce. How much of each commodity would be bought? c. By how much should David's allowance be increased to compensate for the increase in the price of jelly in part (b)?

Would you expect total utility to rise or fall with additional consumption of a good? Why?
Eren’s two main hobbies are taking vacations overseas (V) and eating expensivemeals (M). His utility function is given as: U(V,M) = V2MLast year, the average price of taking a vacation overseas was US$200 and the averageprice of an expensive meal is $50. However, due to supply problems in Onions, theaverage price of an expensive meal rose to $75. The average price of a vacation did notchange. His income, which is $1500, did not change. Calculate for the equivalent variation (EV) for the price change.

4. Kay lives in a city where housing costs $1 per square foot. They have a monthly budget of$1,000, of which they decide to allocate $500 to rent a 500 sqft. apartment and spend teother $500 on consumption. A generous relative offers Kay a deal on a 400 sqft. apartmentfor only $200 per month, which they accept. What is the equivalent variation of this transferfor Kay, in dollars per month? (Select one)(a) More than $300: Kay gets utility from both consumption and the new apartment.(b) $300: That is how much more Kay can consume with the new cost of rent.(c) $250: That is how much less Kay’s old bundle would have cost at the new prices.(d) Between $0 and $250: Kay would substitute away from her old bundle at the new prices.(e) $200: That is the additional cost of Kay’s new bundle at the old prices.(f) Between $0 and $200: Kay may prefer to substitute away from her new bundle at theold prices.(g) $100: That is the differential cost of the new apartment at the old prices.(h) $0: The new…
Eren’s two main hobbies are taking vacations overseas (V) and eating expensive meals (M). His utility function is given as: U(V,M) = V^2MLast year, the average price of taking a vacation overseas was US$200 and the average price of an expensive meal is $50. However, due to supply problems in Onions, the average price of an expensive meal rose to $75. The average price of a vacation did not change. His income, which is $1500, did not change. Suppose that the Department of Welfare wants to know how much should be given to Eren to offset his change un utility due to the price increase of an expensive meal. Calculate the compensative variation (CV).
Amadea spends all her income on pizza,chocolate milk, and music streams. The price of pizza is $4 per slice and price ofchocolate milk $2 per bottle. At Amadea's current consumption level, her marginalutility for pizza is 50 units per slice and for music 100 units per stream. Assuming thatAmadea is a utility maximizer, how much is (a)her current marginal utility for a bottleof chocolate milk, and (b) the price of streams she buys. Show your work. [Hint: Ch 6:Utility-maximizing formula)
Elizabeth makes $200 a week at het summer job and spends her entire weekly income on new running shoes and jeans, since these are only two items that provide utility to her. Furthermore,Elizabeth insists that for every pair of jeans she buys, she must also buy a pair of shoes. (without the shoes, the new jeans are worthless). Therefore, she buys the same number of pairs of shoes and jeans in any given week. a) If jeans cost $20 and shoes cost $20 , how many will Elizabeth buy of each?b) Suppose that the price of jeans rises to $30a pair , how many shoes and jeans will she buy?c) To what effect (income or substitution) do you attribute the change in utility levels between part a and part b

(a) A consumer has utility u(x,y,z) = ln(x) + 2ln(y) + 3ln(z) over the three goods, x,y and z and pz=1. Optimally she consumes 30 units of z. What is her income? How much money does she spend on x? (HINT: MUx = 1/x, MUy= 2/y, MUz = 3/z and remeber the "equivalent bang for the buck" condition). (b) Forget about (a). Suppose you have t= 29 hours in total to spend on 3 projects X,Y and Z to make some money. If you spend x hours on project X, you make 2 sqrt(x) dollars; If you spend y hours on project Y, you make 3 sqrt(y) dollars; If you spend z hours on project Z, you make 4sqrt(z) dollars; Writing down your "utility function" u(x,y,z) and the constraint, solve the utility maximization problem; what is the optimal amount of time to spend on x? on y? on z?
Question Ebrima gets $3 per month as an allowance to spend any way he pleases. Because he likes only peanut butter and jelly sandwiches, he spends the entire amount on peanut butter (at $.05 per ounce) and jelly (at $.10 per ounce). Bread is provided free of charge by a concerned neighbor. Ebrima is a picky eater and makes his sandwiches with exactly 1 ounce of jelly and 2 ounces of peanut butter. He is set in his ways and will never change these proportions. How much peanut butter and jelly will Ebrima buy with his $3 allowance in a week? Suppose the price of jelly were to rise to $.15 per ounce. How much of each commodity would be bought? By how much should Ebrima’s allowance be increased to compensate for the rise in the price of jelly in part b? Graph your results of part a through part c. In what sense does this problem involve only a single commodity—peanut butter and jelly sandwiches? Graph the demand curve for this single commodity. Discuss the results of this problem…
