Missing Dollar Riddle

Question: Three guests check into a hotel room. The clerk says the bill is $30, so each guest pays $10. Later the clerk realizes the bill should only be $25. To rectify this, he gives the bellhop $5 to return to the guests. On the way to the room, the bellhop realizes that he cannot divide the money equally. As the guests didn't know the total of the revised bill, the bellhop decides to just give each guest $1 and keep $2 for himself. Each guest got $1 back: so now each guest only paid $9; bringing the total paid to $27. The bellhop has $2. And $27 + $2 = $29 so, if the guests originally handed over $30, what happened to the remaining $1?

The tip was actually paid by the guest and not the hotel.\nIn essence the Guests paid the bellhop $5 as tip. \nSo each guest paid the bellhop $1.67 as tip. \nSo effectively they paid the hotel $8.33\nWhen they got the $1 back it made it $9.33\nSo the Bellhop's tip is now $0.67.\nSo $9.33 + $0.67 = $10

One does not simply add the $2 to the $27,\nOne subtracts the $2 from the $27, to equal $25

Because there's a flaw in our mathematical system...
