Problem 12 Solution

This is a trick question.

The total money paid is $9 * 3 = $27.

The total money received is $25 for the room and $2 to the bellboy = $27.

There simply is no extra dollar. The $2 to the belloy is included in the $27 the three men paid. By adding it to the $27 it is being counted twice.
