This question is in the rec.puzzles Archive.

To request a copy of the index to the Archive, send a letter to

The Archive has been posted to news.answers.  News.answers is archived in
the periodic posting archive on pit-manager.mit.edu [18.172.1.27].
Postings are located in the anonymous ftp directory
/pub/usenet/news.answers, and are archived by "Archive-name".  Other
subdirectories of /pub/usenet contain periodic postings that may not
appear in news.answers.

Other news.answers archives are:

	ftp.cs.ruu.nl [131.211.80.17] in the anonymous ftp
		directory /pub/NEWS.ANSWERS (also accessible via mail
		server requests to mail-server@cs.ruu.nl)
	cnam.cnam.fr [192.33.159.6] in the anonymous ftp directory /pub/FAQ
	ftp.uu.net [137.39.1.9 or 192.48.96.9] in the anonymous ftp

	grasp1.univ-lyon1.fr [134.214.100.25] in the anonymous ftp
		directory /pub/faq (also accessible via mail server
		requests to listserv@grasp1.univ-lyon1.fr), which is
		best used by EASInet sites and sites in France that do
		not have better connectivity to cnam.cnam.fr (e.g.
		Lyon, Grenoble)

Note that the periodic posting archives on pit-manager.mit.edu are
also accessible via Prospero and WAIS (the database name is "usenet"
on port 210).

From the Archive, the answer is:
********
logic/29.s
********
Each person paid $9, totalling $27.  The manager has $25 and the bellboy $2.
The bellboy's $2 should be added to the manager's $25 or subtracted from
the tenants' $27, not added to the tenants' $27.
