If you have an 82 average that counts as 70 percent of your grade what do you need to make on the test which is 30 percent of your grade. In order to keep a 80 average
=====================================
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%
