You can put this solution on YOUR website! Suze has grades of 94 and 88 on her first two exams. What possible scores on a third test will give her an average that is no less than 90?
-------------------
no less than 90 is 90 or more --> >= 90 greater than or equal to 90
A 90 avg for 3 exams = 270 points (90*3)
94 + 88 = 182
270 - 182 = 88
-------------
If she makes 88, her average will be 90.
Score = 88 for 90 average
Score > 88 for > 90 average
