### #367Hotel Bill

Posted by on 03 May 2007 - 03:07 PM

Actually, I got a totally different answer - and please tell me if I'm wrong:

For the money exchanged: The true bill was \$25 and the bellboy gave each of the three guests a \$1 back. Now, the total exchanged is \$28. And the bellboy has \$2. That equals the \$30.

For the intangible part: You can't figure in that each guest paid exactly \$9 for the room because the room bill was \$25 which can't be divided between 3 people evenly. Each person would have paid exactly \$8.33333333333333 each.

Take the \$8 x's 3 people = \$24
Plus \$3 they were given back = \$3
.33333333333333 x's 3 people = \$1 <--- the missing dollar
and the bellboy has \$2

Total = \$30

- Hope I did this right
