Unable to divide the money three ways, he decides to give $10 to each girl and pockets the remaining $20. The girls have now paid $90 each or $270 for the room, and the room attendant has $20. What happened to the other $10?
There is no other $10. The total was $300, the girls got back $10 each, meaning they paid $270 for the room, and the other guy took the last $20, will adds up to the entire $50 refund. The original $300 is all accounted for. $250 is in the cash register. $30 is with the 3 girls, and $20 is with the clerk.
