Do it like this one.
--------------
I have and 87% as my average grade in math. Finals are worth 15%. How much would I need to score to get at least an 80% as my average in math?
--------------
The 87% is 85% of your grade.
F = grade on Final (or test)
87*85 + F*15 = 100*80
F = (8000 - 7395)/15
F = 40.33%
