- Hello, I am not understanding this practice problem. I dont know how to solve the second half .arrow_forward2. Ping receives a weekly allowance to purchase soda (x) and juice (y) at school. His preferences over these two goods can be represented by the utility function U(x,y) =0.5x+ 5lny where x represents the number of cans of soda and y represents the number of juice boxes. a) Given his preferences find his Marshallian demand functions for soda (x) and juice (y). b) Suppose that the price of a can of soda is $1.5 and that Ping has $30 to spend on soda and juice. Write Ping's demand curve for juice (y). Illustrate his demand curve. c) Suppose that the price of a box of juice is $1 (the price of soda and income remain $1.5 and $30, resp.). Use your demand functions to find his best bundle. In an indifference curve diagram illustrate his best bundle at these prices. For the remainder of the question assume that Ping's allowance (income) rises to $36 per week and the prices of the two goods are unchanged at Px= $1.5 and Py= $1. d) Use your demand functions to find his new best bundle. e)…arrow_forward10arrow_forward
- 1/2 Consider a consumer with the utility function u(x, y) = 2x¹2 + y, an income of I = Rs 100, and price of good y is Rs 1. A) Find the demand functions for goods x and y. B) If, ceteris paribus, price of good x decreases from Rs 4 to Rs 3, what is the compensating variation? 1.arrow_forwardThe utility function is given by u(x₁, x2) = min{2x1,5x2}. a) For this utility derive the demand functions x₁ (P₁, P2, 1) and x₂ (P₁, P2, 1). b) Set l=36 and p2 = 1. Draw the demand curve for good 1. c) Give the formula and draw the Engle curve for good 1. Is good 1 normal or inferior? Are preferences homothetic? Explain.arrow_forwardSuppose your income is 200, the price of good x is 2, and the price of good y is 3. You know that your utility function is U= 2(xy)^3. (A) What amounts of x and y do you choose? (B) Can you generalize your choices to demand curves for x and y for any prices and income?arrow_forward
- Suppose that, by law, a person is required to consume a fixed amount of good X, say X0. Assuming X is a normal good, explain how this law reduces utility for both high and low income people.arrow_forwardA student has a lunch utility function U(S, P) 8S + 3P, where S is number of salads per month and P is number of pizzas per month. The price of a salad is $5, the price of a pizza is 8, and his monthly income for lunch is $80. a) Derive the equation representing the consumer's demand for Salad. Represent the demand for Salad graphically. b) The price of Salad goes up to $25 and the price of Pizza does not change. Compute and represent graphically the new equilibrium of the student. What can you tell about the substitution effect on Salad and pizzaarrow_forwardRicky has utility function u=x'y. This implies that MUx=2xy. MUy=x². His income is 100. The price of y is 10. (a) Find his demand for x at price 20. (b) Find his demand for x at price 30. (c) Write down his demand function for x: that is, write down his demand for x as a function of the price of x.arrow_forward
