George, Jerry, Elaine, and Kosmo are seated in a restaurant figuring out what to order.Carrot cakes cost $2 and pickles cost $1 each. George declares he would like to get three carrot cakes and four pickles. Jerry suggests, why not get two carrot cakes and six pickles, since the marginal utility of carrot cakes diminishes more rapidly. Kosmo says George should order no carrot cakes and 10 pickles, or else 5 carrot cakes and no pickles. George responds that with 10 pickles or 5 cakes, the marginal utility of the last one would be very low. "But the total utility would be greater," says Kosmo. Elaine says that George should get the quantities where the marginal utility of the next cake is double the marginal utility of the next pickle. "You're wrong," says Jerry. "The marginal utility of the cake should equal the marginal utility of the pickle." You are seated in the next table and they ask you what they should do. For rational consumer choice,
George should heed Elaine's advice and get that amount for which the marginal utility divided by the price is equal for the carrot cake and the pickle.
