Suppose that Ben has $90 to spend on two goods, movie (M) and hamburger (H). The price of a movie is $10 and the price of a hamburger is $2. Ben’s preferences are represented by the utility function: U(M, H) = M *H^2 .
(a) What is Ben’s optimal choice between movie and hamburger?
(b) Suppose that the price of hamburger rises to $5. How will this change Ben’s decision?
