Just to clarify...
\n" ); document.write( "After 80% of the course is completed, you have a 75.77 average.
\n" ); document.write( "The final is worth 20%
\n" ); document.write( "80% = a B grade (for many teachers, it's 84, but we'll use 80)
\n" ); document.write( ".
\n" ); document.write( "8 grade-tenths * 75.77 = 60.616
\n" ); document.write( "2 grade-tenths * x = 80 - 60.616 or 19.384
\n" ); document.write( "Divide by .2
\n" ); document.write( "You'll need 96.92 on the final to get a B in the class
\n" ); document.write( "
\n" );
