Step-by-step explanation:
The concept of marginal thinking is highly relevant in various real-life scenarios. Marginal thinking involves analyzing the additional costs and benefits of making small changes in the level of an activity or resources used.
In the context of the question, marginal thinking could help improve the results of studying by evaluating if the additional hour spent on a certain subject justifies the expected improvement in grades. When it comes to driving, it could involve deciding whether the benefit of taking a slightly longer but less congested route is worth the extra time spent. In shopping, marginal thinking could help determine if buying an item at full price now provides more utility than waiting for a sale or purchasing an alternative. Lastly, while looking for a place to park your car, it can assist in weighing the costs such as time and money against the convenience of parking closer to the destination. Therefore, the correct answer to the question is e. All of the above.
