Each man pays $10 each and goes to the room.
Later that evening, the night manager comes in and finds out that the day person overcharged the 3 men by $5
He sends the bellhop to the mens room to give them back the five dollars. The bellhop figures it is too hard to divide the $5 to the three men so he keeps $2 for himself and gives each man a $1.
Each man paid $10 but received a $1 back for a total of $9 each
The bellhop keeps $2 for himself.
Where did the other dollar go?
3 x $9 = $27 + $2 = $29
The last equation is incorrect.
After the refund, they'd paid $27 for a $25 room. That left $2 for the bellhop. The proper equations should be:
3 x $9 = $27
$27 - $2 = $25
That could be written (incorrectly) as:
3 x $9 = $27 - $2 = $25
It's incorrect to write that way because the left equality doesn't hold true ( 3 x 9 does not equal 27 - 2 ). That's not the heart of the problem, but it does make it more confusing. A more proper way to write this is:
3 x $9 = $27 = $25 + $2
That shows the final disposition of the transaction, and all equal signs are between equal quantities (as they should be). The three men (left) paid $9 each for a total of $27. That money was split (right) with $25 for the hotel and $2 for the bellhop.
At the time of this posting there's been no solution posted to the Oz Form.
