Ross derives utility from only two goods, chocolates (x) and donuts (y). His utility function is as follows: U(x,y) = 2xy. His marginal utility from chocolates (x) and donuts (y) are given as follows: MUx = 2y and MUy = 2x. Ross has an income of $100 and the price of chocolates (Px) and donuts (Py) are both $0.50. b. Suppose the price of donuts (Py) increases to $0.80, the price of chocolates and income remain unchanged. How much is the total effect of this price change on Ross's consumption of donuts? Show your work. How much of this total effect is due to the income effect and how much is due to the substitution effect? Show your work.

Suppose that Sally's preferences over baskets containing coffee (good x), and milk (good y), are described by the utility function U(x,y) = 40x+y. Sally's corresponding marginal utilities are MUx=40 and MUy=1. The price of coffee is Px = $4 per cup, and the price of milk is Py = $1 per litre. Sally's income is I = $200.

Question 1: Without deriving the optimal consumption basket, show that the basket with x = 25 cups of coffee, and y = 50 liters of milk, is NOT optimal. (3 Marks)

Question 2: Derive the expression for Sally's marginal rate of substitution. (1 Mark)

Question 3: Find Sally's optimal consumption basket. (3 Marks)

Question 4: Find Sally's new optimal consumption basket if the price of coffee increases to Px = $5 per cup. (3 Marks)

Question 5: Is coffee a Giffen good for Sally? Briefly explain. Your answer must reference the consumption baskets you found in questions 3 and 4. (3 Marks)

Question 6: Find the income and substitution effects associated with an increase in the price of coffee from $4 to $5 a cup. (4 Marks)
