What happen if the overall total is 113.05?

To determine Marissa's course average, we need to calculate the weighted average of her attendance, quizzes, exams, and final exam scores.

First, let's calculate the weighted average for each category:

Weighted average for attendance:
Attendance score * Weight for attendance = 100% * 5% = 5

Weighted average for quizzes:
Quiz score * Weight for quizzes = 93% * 15% = 13.95

Weighted average for exams:
Exam score * Weight for exams = 82% * 60% = 49.2

Weighted average for the final exam:
Final exam score * Weight for the final exam = 81% * 20% = 16.2

Next, sum up the weighted averages for each category:
5 + 13.95 + 49.2 + 16.2 = 84.35

Finally, divide the sum by the total weight percentage to get Marissa's course average:
Course average = Sum of weighted averages / Total weight percentage
Course average = 84.35 / 100% = 84.35

Therefore, Marissa's course average is 84.35.
