3 people go to a hotel
At the counter, the assistant charges them $30 in total, each person pays $10.
Later that day, the manager decides to put a $5 discount on the price, so that it costs $25.
The assistant is to return $5 to the 3 people, but he sneakily takes $2 for himself, leaving $3 for the 3 people.
Each of the 3 people recieves $1 of the $3, and therefore, they are each paying $10 - $1 = $9
but wait..... $9 x $3 = $27... add on the $2 took = $29.. where did that $1 go?????
saw this in an email... it looks a bit suspicious to me.. but i still can't figure how this extra $1 came to be.
