Give the step-by-step reasoning process and then the final answer. Maddy is in college for 8 semesters. She needs 120 credits to graduate. If each class is 3 credits, how many classes does she need to take per semester?
120 credits / 3 credits is 40. 40 credits / 8 semester = 5 classes per semester. Maddy needs to take 5 classes per semester.
The final answer: 5.
