document.write( "You have TWO DIFFERENT kinds of wages in this problem.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "One wages is \"hourly wages\": they decreased by 15%.\r\n" );

document.write( "\r\n" );
document.write( "The \"old\", the original \"wages for the period of duty\" was 56*h, where h is the old \"hourly wages\".\r\n" );
document.write( "\r\n" );
document.write( "The new \"wages for the period of duty\" is 72*H, where H is the NEW \"hourly wages\".\r\n" );
