Question 199542: What property is violated here?
“THE MISSING DOLLAR” SaveAs: TheMissingDollar
Three men went to stay at a motel, & the man at the desk charged them $30.00 for their room. They split the cost, paying $10.00 each.
Later, the manager tells the desk man that he overcharged the men – that the actual cost should have been $25.00. The manager gives the bellboy five one-dollar bills, and tells him to give it to the men.
The bellboy figures – these guys didn’t give me a tip, & there’s no way I can evenly split five dollars three ways, so he stuck $2.00 in his pocket, & returned $3.00 to the men.
Now, each man has paid $9.00 to stay in the room; [3 men] [$9.00 each] = $27.00.
The bellboy pocketed $2.00; [$27.00] + [$2.00] = $29.00.
[$29.00] – [$30.00] = - $1.00.
WHAT HAPPENED TO THE MISSING DOLLAR ?
Thanks,
Ken Crook
