Answer:

There's a very simple way to solve this kind of problem. All we have to do is change the percent to a decimal and multiply it by her current grade.

81 × .15 = 12.15

For our purposes, we'll just round it down to 12. But anyway, raising her grade by 15% would mean raising it by 12 points.

81 + 12 = 93

This would give her an average of 93, not 95. She'd need to raise her grade 18% from 81 to get to her goal.
