\r\n" );
document.write( "Let \"x\" be the volume of the 0.2% butterfat milk needed.\r\n" );
document.write( "\r\n" );
document.write( "Then the volume of the 3.4% butterfat milk needed is (260-x).\r\n" );

document.write( "\r\n" );
document.write( "0.002x + 0.034*(260-x) = 260*0.01.\r\n" );

document.write( "Multiply both sides by 1000. You will get an equivalent equation\r\n" );
