17. MRS and utility maximization Yakov lives in New York City and loves to eat desserts. He spends his entire weekly allowance on yogurt and pie. A bowl of yogurt is priced at $1.75, and a piece of apple pie is priced at $7.00. At his current consumption point, Yakov's marginal rate of substitution (MRS) of yogurt for pie is 3. This means that Yakov is willing to trade three bowls of yogurt per week for one piece of pie per week. Does Yakov's current bundle maximize his utility---in other words, make him as well off as possible? If not, how should he change it to maximize his utility? Yakov's current bundle maximizes his utility, and he should keep it unchanged. Yakov could increase his utility by buying more yogurt and less pie per week. Yakov could increase his utility by buying less yogurt and more pie per week.
