In​ Marissa's calculus​ course, attendance counts for 5%  

of the​ grade, quizzes count for 

10% of the​ grade, exams count for 60% and the final exam counts for 25% Marissa had a 

100% average for​ attendance, 

93% 

for​ quizzes, ​% 

for​ exams 86% , and 

81​% 

on the final. Determine​ Marissa's course average.



To determine Marissa's overall course average, we will calculate a weighted average based on the given percentages for each category:

- Attendance: 5% of the grade
- Quizzes: 10% of the grade
- Exams: 60% of the grade
- Final Exam: 25% of the grade

The grades for each category are:
- Attendance: 100%
- Quizzes: 93%
- Exams: 86%
- Final Exam: 81%

To calculate the weighted average:

\[
\text{Course Average} = (100 \times 0.05) + (93 \times 0.10) + (86 \times 0.60) + (81 \times 0.25)
\]

Let me calculate that for you.Marissa's overall course average is **86.15%**.
