What are some examples of opportunity costs and how do they impact decision-making?

Opportunity costs are the benefits that are forgone when choosing one option over another. For example, if you choose to go to a concert instead of studying for an exam, the opportunity cost is the potential higher grade you could have achieved by studying. Another example is choosing to spend money on a vacation instead of saving for a new car, where the opportunity cost is delaying the purchase of the car. Understanding opportunity costs helps individuals make more informed decisions by weighing the benefits and drawbacks of each choice.
