) = N 's“, where 0 < a <1 and N > 0. The price of jam is pj, the price of sandwiches is Ps, and Joey monthly budget Y to spend on lunch. Explain why you can safely use a simpler Cobb-Douglas utility function, V(j, s), to represent Joey's preferences, which is the same as U(j, s) except for replacing N with 1. Transform V (j, s) by taking natural logs and bringing down exponents. Explain why it is useful to do this for a Cobb-Douglas utility function, but not for a quasi-linear utility function. Use In(V(j, s)) and the substitution method to derive the formulas for Joey's optimal amount of jam, j*, and sandwiches, s*, to buy and consume per month. Simplify your answers so that you arrive at the (1-a)Y formulas j* aY and s* = Ps Pj
