Trying to figure out test scores.
You take a 14 week course in which your overall test score must average at 70% or above. The first 13 weeks, you take 9 tests. The 14th week, you take a comprehensive final makes up 30% of your overall test score average. How can you find out what you need to score on the comprehensive final to keep a 70% test score average based on the test score average of the 9 tests previously taken?
