Understanding the Answer
Let's break down why this is correct
Answer
Marginal analysis is a way to evaluate the benefits and costs of a decision by looking at the additional or "marginal" effects. In this case, the student chose to study for an extra hour, which improved their understanding of the material, likely increasing their chances of doing well on the exam. However, this decision also meant they missed out on a social event, which could have provided enjoyment and relaxation. To classify this decision, we would weigh the benefit of better exam preparation against the cost of missing the social event. If the student believes that the improvement in their exam performance is worth more than the fun of the event, then they made a rational choice based on marginal analysis.
