Re: The missing dollar problem

Ron Someone before inquired about the solution to this problem. It seems to me that if the clerk overcharged the friends by five dollars, the origional price of the room would then be $25. But the friends "gave" the son a two dollar tip. Thus the $27 for the room they paid. I'm not sure if you were the one that posted the question, but I'm thinking this may be the solution. My $0.02 worth. Dave Leom On Mon, 13 Mar 1995, Ronald A Ward wrote:
