You can put this solution on YOUR website!
theres alot of unknowns here...like what percentage is the lowest B for your class. some classes ive been in ranged for lowest: 84.5%, 80%, or 79.5%.
if i knew how many points made up that 81% and how many points made up the exam plus the lowest B% I could give you the exact percentage and points needed. but this question is to vague to answer.
this would be my best guess with the standard 80% being lowest B
%2881%2B81%2B81%2Bx%29%2F4=80
%28243%2Bx%29%2F4=80
%28243%2Bx%29=320
x=77
so atleast a 77% on the exam
