\r\n" );
document.write( "Take x kilograms of thedark chocolate and (40-x) kilograms of the white chocolate.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the cost of the mixture will be  80x + 40*(40-x), so you have this cost equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    80x + 40*(40-x) = 55*40.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the equation,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x =  = 15.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  15 kg of the dark chokolate and the rest, 40-15 = 25 kg of the white chocolate.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   = 55 Php per kilo of the mixture.  ! Correct !\r\n" );
