    The answer is C. Mrs. Green should spend more on soda and less on pretzels.

    Explanation:

    Marginal utility-price ratio = marginal utility of a generic good / price of a generic good

    Soda Marginal utility-price ratio = 60 / 0.60 = 100 utils per dollar

    Pretzels Marginal utility-price ratio = 30 / 0.40 = 75 utils per dollar

    Mrs. Arnold should choose soda as it has a higher marginal utility-price ratio than that of pretzels.
