4. Suppose Michelle's tastes for haircuts (x1) and spending on other goods (x2) per year can be represented by the separable utility function u(x1, x2)=600x1" + 2x2. (a) Derive an expression for Michelle's marginal rate of substitution (MRS). (3 marks) (b) Derive expressions for Michelle's optimal bundle of x and x2 by simply using the fact that, at any interior solution, MRS = -pi/p2. (4 marks) (c) What slope does Michelle's demand curve for haircuts have (e.g. downward-sloping, upward-sloping, horizontal, vertical)? (2 marks) (d) Suppose haircuts cost $50 each and Michelle's income is $80,000, how many haircuts (x1) does Michelle consume? (2 marks) (e) How much money does Michelle spend on other goods (x2)?
