Mathematical untruth riddle
#1
This Saturday I was at a friends house, and her mom told me this insane riddle. At first I was baffled, but it's actually simple. See if you can figure it out!

Quote:
There are three people going to stay at a motel. The cost is $30. The three people decide to split the cost, each paying $10.

Upon arriving at the motel, the bus boy says that the price has been lowered to $25. Since they had already paid, he needed to give them $5.

The three people decided to each take $1 each and give the remaining $2 to the bus boy as a tip. This means they each paid $9 rather than $10 because they were all given $1 back.

If each person paid 9$, then they paid 27$ in total (9*3). Add that to the $2 they gave the bus boy, and you only get 29$.

Where did the last $1 go?
