Question

If a student scored an average of 60% on a test, what score would he/she need to average it out to a passing 80+. What formula would you use. This isn't a question on a test, it's one I've been trying to find. I am able to retake a test multiple times and will average itself out. It is averaged out to a 60. What score will I need to average it out to 80+ and what formula would I use to figure this out so I may use it on other tests?

Answer 1

Two tests = 200

0.8 * 200 = 160

160 - 60 = 100

The student needs to score 100 so that the two tests average 80.
