the final grade for a particular course is calculated by dividing total points earned by total points available. There are 6 quizzes worth 15 points each, and 2 exams worth 50 points each. If a student earns 67 points total on the quizzes and wants to get at least 86% in the course, at least how many points must they earn on the exams in total?

Total possible points = 6(15) + 2(50) = 190
190 (.86) = 163.4
67 + x ≥ 163.4
Solve for x.

Sorry, I pasted the wrong info previously.
If you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
