document.write( "Since the combined weight of one large box and one small box is 80 pounds,\r\n" );
document.write( "\r\n" );
document.write( "50 large boxes and 50 small boxes  weight  50*80 = 4000 pounds, combined.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that remaining 60-50 = 10 large boxes weight 4500-4000 = 500  pounds.\r\n" );

document.write( "Hence, one large box weights 500/10 = 50 pounds.\r\n" );
