I need help with this one ASAP:
3 guys decide to rent a room while traveling. They are told the room is $30, so they equally divide the room to be $10 per guy. In the course of registration, the manager says they are offering a discount, the room will be $25. To aid them in splitting the difference, the owner said I will keep $2 and you will each get $1 back. That would make their share $9 per guy. $9 x 3 = $27. If the owner kept $2, what happened to the other dollar??????
