A riddle for you guys.
Apollo:
I've never seen this but is the misdirection that they actually paid $8.33333 each for the room not $9?
so 3 * 8.33333 = $25 plus the $2 for the hop and their $1 each = $30?
_) (V) (-):

Into the change machine for tokens of course.
Duh! ;)
cdbrown:
Easy way to explain is they each paid $9 - that went towards the $2 for the tip and the rest for the room.
More Cowbell:
Yeah, the misdirection is in the $27+$2 to get to $30. You're really trying to get to $25 which is the new price of the room. So $9x3=$27 minus $2 for tip = $25.
Spaz Monkey:
Original room cost $30 = 3 guys @ $10ea
New room cost $25 = 3 guys @ $8.33333 ea plus $1 refund for each guy ($3) and $2 tip.
I'll use _ as the "repeat untill infinity" mark here.
You can't divide 1 by 3. Look up on wikipedia "0.999...". You'll see an entry that talks about why 0.33_ *3 = 1.0
