document.write( "Let x be the number of passengers in 2005.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the number of passengers in 2006 was  x*(1+0.08) = 1.08x,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and the number of passengers in 2007 was 1.08x*(1+0.08) =  = 1.1664x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The increase from 2005 to 2007 was  1.1664x - x = 0.1664x,\r\n" );
