\r\n" );
document.write( "\r\n" );
document.write( "Let x be the amount of the Php80 chocolate in the mix (in kilograms).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the amount of the Php60 chocolate in the mix is the rest (24-x) kilograms.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The total cost of the mix then is  80x + 60*(24-x).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Per kilogram, the price of the mix is  .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We want this price would be Php72.50 .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives you an equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     = 72.50.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve it, multiply both sides by 24 and then simplify step by step\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    80x + 60*(24-x) = 24*72.50\r\n" );
document.write( "\r\n" );
document.write( "    80x + 60*24 - 60x = 24*72.50\r\n" );

document.write( "    20x = 24*7250 - 24*60\r\n" );
document.write( "\r\n" );
document.write( "    x =  = one click in Excel = 15.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  15 kilograms of the  Php80 chocolate and  24-15 = 9 kilograms of the Php60 chocolate.\r\n" );
