Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
example: 100 points for class
80 for everything before final exam and 20 for exam
.8(80)=64
((64+x)/100)100=80%
64+x=80
16=x
16/20=80%
so u need an 80% grade to keep an 80%in the class
since you gave no values i cannot determin the exact score but basically its
.8 times total points = amount of points needed on test.
