i think it works like this.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "total sales for the month were 21500.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "total returns for the month were 325.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "total net sales for the month were 21500 minus 325 = 21175.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7000 of that was commissioned at 7.5%.
\n" ); document.write( "8000 of that was commissioned at 9%.
\n" ); document.write( "21175 - 15000 = 6175 of that was commissioned at 11%.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "his total commission for the month was .075 * 7000 + .09 * 8000 + .11 * 6175 = 1924.25.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "his gross earnings for the month were 1924.25.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
