Question
Sally consumes two goods, X and Y. Her utility function is given by the expression U(X, Y) = 3XY². The current market price for X is $10, while the market price for Y is $5. Sally's current income is $500.

a. Write the expression for Sally's budget constraint. Graph the budget constraint and determine its slope.

b. Determine the X*, Y* combination which maximizes Sally's utility, given her budget constraint. Show her optimum point on a graph. (Partial units for the two quantities are possible.)

c. Calculate the impact on Sally's optimum market basket of an increase in the price of X to $15. What would happen to her utility as a result of the price increase? Be specific.
