he gained 10% on one of them.
\n" ); document.write( "x + .10 * x = 1200
\n" ); document.write( "combine like terms to 1.10 * x = 1200
\n" ); document.write( "solve for x to get x = 1200 / 1.10 = 1090.909091\r
\n" ); document.write( "\n" ); document.write( "he lost 10% on the other of them.
\n" ); document.write( "x - .10 * x = 1200
\n" ); document.write( "combine like terms to get .9 * x = 1200
\n" ); document.write( "solve for x to get x = 1200 / .9 = 1333.333333\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x represents the cost.
\n" ); document.write( "total revenue is 2400
\n" ); document.write( "total cost is 2424.242424\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "revenue / cost = 2400 / 2424.242424 = .99\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "greater than 1 he made a profit.
\n" ); document.write( "less than 1 he took a loss.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1 - .99 = .01 = 1% loss.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he took a loss of 1%.
\n" ); document.write( " \n" ); document.write( "
\n" );
