In other words:

They each payed $10 dollars, so $\displaystyle $10 \cdot 3 = $30 $

They each got $1 back, so $\displaystyle (10-1) \cdot 3 = 27 $

and the bellboy keeps $2, $\displaystyle 9 \cdot 3 + 2 = 29 $

Now the question: What happened to the extra dollar?

Here is a riddle that I like and it stumps a lot of people, let's see how you guys do.
