\n" ); document.write( "56000-x at 6% makes 3360-0.06x per year
\n" ); document.write( "they add to 3200
\n" ); document.write( "so 3200=-0.01x+3360
\n" ); document.write( "0.01x=-160
\n" ); document.write( "x=$16000 @5%=$800
\n" ); document.write( "56000-x=40000@6%=$2400
\n" ); document.write( "they add to $3200.
