Math riddle! !

3 guys walk into a hotel. the hotel charge was $30. each guy payed $10. the owner felt bad bc they were such nice guests. so the owner gave $5 to the bell boy to give to the guys. the bell boy thought for a moment. you can't split $5 w/ 3 guys ( w/ 5 singles quickly ) so he took $2. so he gave the guys the $3. they each get $1 back. so they each paid $9 ( $27 total ) the bell boy took 2 and they paid 27 ( $29 total ) what happened to the other dollar?

The method for working out how much they each paid is incorrect, lets look at it from a different perspective.

The 3 guys paid him $30, now he gives back $5 to the guys.

So there is $25 with the owner and $5 with the bell boy.

Now the bell boy keeps $2 and gives back $3, $1 to each of the guys.

So there is $25 with the owner, $2 with the bell boy and $3 with the guys.

Now indeed the guys paid $30 - $3 which is $27 dollars, but we can see that that is now split between the owner and the bell boy as $25 + $2 = $27 dollars.

I'm sure the answer is a
