Question 1036755: An average score of 90 or above in a math class receives an A grade. You have scores of 94, 86, and 83 on three exams. Find the range of scores on the fourth exam that will give you an A grade for the course. Let N stand for your score on the fourth exam Answer by FrankM(1040) (Show Source):
You can put this solution on YOUR website! To average 90, the 4 scores must add to 360 (right?)
94+86+83 add to 263 and 360 - 263 = 97.
It will take 97 or higher to get a 90 average (or greater)
