Question 882961: If I have a weighted grade of 98% in a class and don't do a final project worth 20% what will my grade be? Answer by cigany29(23) (Show Source):
You can put this solution on YOUR website! If your final project is worth 20% of your final grade, then your mark of 98% is worth the remaining 80% of your grade.
98(0.8)=78.4
SO if you decide not to do the final project your final grade will be 78.4 percent.
