Answer by hovuquocan1997(83)   (Show Source):
You can put this solution on YOUR website! Your scores for the first three quizzes are 85, 68, 90, so the total points you have so far is:
 points
You need at least 320 points, and now you only have 243 points, that means on the last test, you have to get at least 77 points because
So the range of scores you can get on the last quiz that will give you an overall B is from 77 to 100
I hope this answer is helpful :)
