You can put this solution on YOUR website!
you got a 45% on your final.
\n" ); document.write( "you had 77% going in to the final.
\n" ); document.write( "the final is worth 20% of your grade.
\n" ); document.write( "this means the 77% was worth 80% of your grade, since 80% plus 20% = 100% of your grade.
\n" ); document.write( ".80 * 77% + .20 * 45% = 70.6%
\n" ); document.write( "as far as i can see, your final grade should be equal to 70.6% if that's all that goes into it.
\n" ); document.write( "
\n" ); document.write( "
