You can put this solution on YOUR website! I have a 60% and need 70% to pass. My final is worth 15% of my grade. What do i need to get on final?
--------------
60*85 + F*15 = 70*100
15F = 1900
F =~ 127
Good luck with that.
---------------
If you get 100 on the final
60*85 + 15*100 = G*100
Grade = 66
