Both products
Understanding the Answer
Let's break down why this is correct
Answer
Both products give the same utility per dollar (20/20 = 1 and 30/30 = 1), so the consumer’s marginal utility per dollar is equal. However, buying Product Y gives 30 units of utility while buying Product X gives only 20 units, so the opportunity cost of choosing X is the extra 10 units of utility that Y would provide. Because the consumer can only buy one product, they should choose Product Y to maximize total utility while still spending the same amount per unit of utility. In short, Product Y is the better choice because it delivers more utility for the same dollar‑worth of spending.
Detailed Explanation
Both products give the same utility per dollar, but Product Y gives more total utility. Other options are incorrect because Choosing X because it is cheaper ignores the fact that you lose 10 units of enjoyment; Skipping both means you keep all money, but you miss the chance to enjoy anything at all.
