<PRE><B>Question 541843</B>
if i have a 81 in a class and my exam is worth 20% what do i need to make to keep my 80
-------------
You wanna keep 81?  Or 80?
The 81% is the average of 80%, or 4/5 of the grade
Anyway, (81*4 + score)/5 = 80
324 + score = 400
score = 76% to average 80% overall
76%
--------------
To maintain 81%, you have to make 81%
