Quoting my own work(grammar is terrible hehe)

There was three (3) men, they each paid $10 each for a total of $30 for a hotel room. They got their room and the Hotel clerk says wait a second I overcharged them so he gives the Bellhop $5 to give the 3 men, so he's figuring out a way to detribute the $5 evenly so he puts $2 in his pocket and gives each of the three men a dollar back so they paid $9 each, what's $9 x 3 + $2? what happened to the other dollar?
