A week later, two of the three peopele returned to the hotel and
got the same room. The clerk again charged $30 and again after
realizing the mistake, gave the bellboy $5 to take to the room.
This time, the bell boy gave each of them $1 back and kept the
remaining $3.

Therefore, each person paid $14 for the room, and the bell boy
kept $3, totalling $31. Thus, the "missing" dollar has been
found.
