If a firm's output level is analogous to a student studying for a test, the point where the firm maximizes profit (marginal revenue equals marginal cost) is similar to which of the following for the student?

If we think about a firm trying to maximize profit, we can compare it to a student studying for a test. Just like a firm wants to find the best level of output to make the most money, a student wants to find the best amount of time to study to get the highest grade. The point where a firm maximizes profit happens when the extra money made from selling one more product (marginal revenue) is exactly equal to the extra cost of making that product (marginal cost). Similarly, for a student, the best study time is when the extra effort they put into studying (like reading one more chapter) gives them just enough benefit (like improving their understanding or their grade) without being too tiring or overwhelming. For example, if a student studies for three hours and feels confident, but studying for four hours makes them too tired and less focused, they would find that three hours is their optimal study time, similar to a firm finding its best output level.
