= 8. Jane lives in a dormitory that offers soft drinks and chips for sale in vending machines. Her utility function is U 3SC (where S is the number of soft drinks per week and C the number of bags of chips per week), so her marginal utility of S is 3C and her marginal utility of C is 3S. Soft drinks are priced at £0.50 each, chips £0.25 per bag. a. Write an expression for Jane's marginal rate of substitution between soft drinks and chips. b. Use the expression generated in part (a) to determine Jane's optimal mix of soft drinks and chips. c. If Jane has £5.00 per week to spend on chips and soft drinks, how many of each should she purchase per week?

QUESTION 4 Linguini and Colette consume only éclair (x,) and profiterole (x2). Linguini has utility function UA = x4x4 and Colette has utility function UB = 2xfx. Linguini is endowed with 10 éclair (x,) and 3 profiterole (x), while Colette is endowed with 20 éclair (x,) and 9 profiterole (x2). (a) Draw an Edgeworth box with x, on the horizontal axis and x, on the vertical axis. Position Linguini on the bottom left corner and Colette on the top right comer. Indicate the total number of units of x, and x2. Label the endowment allocation. (b) Derive the equation of the contract curve, ie., find x(x). In your graph in (a), draw the contract curve.
1. Jan has the following utility function for broccoli: U(B) = 54B - 0.5B³ a) What is Jan's marginal utility function?
Suppose Al is currently consuming five movies and two concerts per month. If his utility function is given by U = 15MC, where Mrepresents the number of movies seen and C represents the number of concerts attended, Al's total utility is equal to: 75 15 150 10 30
Can marginal utility be negative? Briefly explain with an example
1. Doreen is looking for a flat to rent in Brighton. a. In choosing a flat, she cares about two characteristics: the number of bedrooms (x), and the number of bathrooms (y). Her utility function is U(x,y) = min(x, 2y). She has £1000 to spent on rent per month. The rental price per bedroom in Brighton is £400, and the price per bathroom is £200. (For example, a flat with three bedrooms and two bathrooms would rent for £1600 per month.) How many bedrooms and bathrooms does Doreen choose to rent optimally? b. Doreen now needs to furnish her flat. She has £500 to spend. However, she would also like to buy some clothes for her new job. The cost of furniture f is £50 per unit and the cost of clothing c is £20 per unit. Her utility function over furniture and clothing is U(f.c) = f0.3c0.7. How much does she spend in total on furniture, and on clothing? c. The local furniture shop runs a flash sale of 50% off, on all prices. How much does Doreen now spend on furniture, and on clothing?…
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. Suppose that the Department of Welfare wants to know how much should begiven to Eren to offset his change un utility due to the price increase of an expensivemeal. Calculate the compensative variation (CV).
