Helen is a computer analyst earning $750,000 a year in New York and flies each winter weekend to Florida to bask in the sun. The price tag is $1,500 . Her cousin Fred is a nursery school teacher earning $35,000 a year in Chicago and spends his winter weekends going to avant-garde movie theaters. The price tag is $20 . Who gets the better deal? a. Helen gets the better deal because the marginal

utility of the Florida weekend is higher than the weekend of movies, regardless of the price tags. b. Helen gets the better deal because the ratio of marginal utility to price is higher than the ratio of marginal utility to price for a weekend of movies. c. Fred gets the better deal because the ratio of marginal utility to price is higher than the ratio of marginal utility to price for a Florida weekend. d. Using interpersonal comparisons of utility, it is clear that Fred gets the better deal because the difference in price overwhelms any difference in the marginal utility of aweekend of movies compared to a weekend in Florida. e. It is impossible to say who gets the better deal because we can't engage in interpersonal comparisons of utility.
