Suppose that in your precalculus class, the final grade is based on four categories. The categories are homework, tests, labs, and a final exam. The final average for the course is the weighted average of scores
earned in these categories with the following weights.
Category
Weight
Homework
20%
Labs
5%
Tests
10%
Final Exam
65%
Suppose you've earned the following grades on each of the categories so far:
Homework
89%
Labs
53%
Tests
53%
The final exam has not yet taken place. Is it possible for you to earn a 80% course average? If yes, what
score do you need to get on the final exam?
Round your answer up to the nearest whole number (between 0 and 100).
If it is not possible to earn a 80% course average, just enter DNE (which stands for "does not exist").
Your final exam score needs to be:
_%
