let x be the number of those graduating
\n" ); document.write( ":
\n" ); document.write( ".75x took 8 math course
\n" ); document.write( ":
\n" ); document.write( "remaining students would be .25x
\n" ); document.write( ":
\n" ); document.write( "so .6(.25x)=.15x
\n" ); document.write( ":
\n" ); document.write( "so .75x have taken 8 courses and .15x have take 6 or 7
\n" ); document.write( ":
\n" ); document.write( "what we have remaining is x-.75x-.15x=.1x
\n" ); document.write( "or 10% of the graduating class have taken fewer than 6 math courses
\n" ); document.write( "
\n" );
