Question 84475: Three friends check into a single room in a motel and pay $10 apiece. The room cost $25 instead of $30, so the clerk is sent to the room to give back $5. The friends each take back $1, and the clerk is given a $2 for his trouble. Now each of the friends paid $9, a total of $27, and the clerk received $2. What happened to the missing dollar?

You can put this solution on YOUR website! Let's see if I understand this correctly. They each paid $9 for a total of $27. Of that amount
$2 went to the clerk and $25 went for the room. What missing dollar?
.
This is an old, old puzzle that never fails to confuse people. You subtract the amount that
is given to the clerk, not add it to the amount they paid ($27) in an attempt to make it
add up to $30.
