Assignment Prompt:<br/>You have 8 hours to study for two final exams.

The exam for course A is worth 25% of your grade and the exam for course B is worth 50% of your grade. The first hour you spend on studying for either exam will increase your score on it by 10 percentage points, the second hour will increase your grade on it by an additional 9 percentage points, the third hour will increase your grade on it by an additional 8 percentage points, and so forth. How will you allocate your time? Explain your answer in terms of marginal analysis.

How do I calculate the marginal cost and marginal benefit with the information I have been provided? If my control variable is the number of study hours I will allocate to each exam, where do I go from there?
