Use percent and 85% of the grade is accounted for, and it is a 78, so the points are 78*85=6630\r
\n" ); document.write( "\n" ); document.write( "Points needed where 100% of the grade is a 75 are 75*100=7500\r
\n" ); document.write( "\n" ); document.write( "Points needed to get there are 7500-6630=870
\n" ); document.write( "Points needed are P*15=870
\n" ); document.write( "p=870/15=58 is the minimum score.
\n" ); document.write( "
\n" );
