Jane's utility function is U = 4XY, where X= number of sandwiches per week and Y = number of salads per week. a. What are Jane's marginal utility of X and marginal utility of Y? b. What is Jane's marginal rate of substitution of sandwiches for salads (if salads are on the y- axis and sandwiches are on the x-axis)? c. Jane's income is $400, the price of a sandwich is $2, and the price of a salad is $4. How many sandwiches and how many salads does Jane consume to maximize her utility? d. When the price of a sandwich is $1, what is her new optimal bundle? e. Plot a graph and show your optimal bundles in parts (c) and (d) on the same graph.

4. John has a utility for the quantity of sandwiches, Xs, and quantity of burgers, Xp, that he consumes, represented by the following equation: U(X,X) = XX His income is Y = $24. The price of a sandwich changes from X, = $1 to X, = $4 while the price of a burger remains at X, = $6. Solve for the compensating variation and equivalent variation associated with this price increase.
Lisa consumes only two goods, pizzas and burritos. In equilibrium, her marginal utility per slice of pizza is 10 and her marginal utility per burrito is 8. Instructions: Enter your answer rounded to two decimal places. If a slice of pizza costs $3, then the price of a burrito must be $
If consumers buy less of a commodity when their incomes rise, this commodity is ( an inferior good , or a normal good ) ? . When the price of this commodity rises, the substitution effect is ( negative or postive) and the income effect is ( negative or postive) ? . So the net result for consumption of this commodity ( depends on which effect dominates , is an increase , is a decrease) ? .

8. Fabian consumes X and Y and the following utility function represents his utility: U = 2XY a. With a utility function of U = 2XY, Fabian's MU, = 2Y and his MU, = 2x ,where MU is marginal utility. Write an equation for Fabian's marginal rate of substitution (MRS). b. Suppose Fabian's income is $120 and Px = S6 and Py-$2, where Px is the price of X and Py is the price of Y. Write an equation for Fabian's budget constraint. c. Write the equation that equates the slope of Fabian's budget constraint to the slope of Fabian's indifference curve: d. If Fabian is spending all of his income, how much X and how much Y will he choose? Use the equations you wrote in part's b and c to answer this question. e. What will Fabian's utility be with this combination of X and Y? f. Now suppose the price of X increases to P.=10.
