Question

Assume that to earn a B grade or higher in a college course you need at least an average of 80% on the five exams that are each worth 100 points. You have scores of 76, 81, 78, and 77 so far in the semester. What is the lowest score you can receive on your fifth exam in order to earn an B grade?

Answer 1

So getting an 80% means that you would have to receive...

80 x 5 = 400 out to the possible 500 points given

76+81+78+77 = 312

400 - 312 = 88

You will need 88 points out of the 100 points on the test (88%).

answer: 88%

Answer 2

The answer your looking for is 88%
