2. Sally consumes two goods, X and Y. Her utility function is given by the expression U = 3XY². The current market price for X is £10, while the market price for Y is £5. Sally's current income is £500. (a) Sketch a set of two indifference curves for Sally in her consumption of X and Y. (b) Write the expression for Sally's budget constraint. Graph the budget constraint and determine its slope.. (c) Determine the X,Y combination which maximises Sally's utility, given her budget constraint.

![2. Sally consumes two goods, X and Y. Her utility function is given by the expression U = 3XY². The
current market price for X is £10, while the market price for Y is £5. Sally's current income is £500.
(a) Sketch a set of two indifference curves for Sally in her consumption of X and Y.
(b) Write the expression for Sally's budget constraint. Graph the budget constraint and determine
its slope.
(c) Determine the X, Y combination which maximises Sally's utility, given her budget constraint.
(d) Calculate the impact on Sally's optimum market basket of an increase in the price of X to $15.
