From 1 to 100

[Nameless]

if its $2 she kept then that means the men paid $28, but the mens only paid $9 each. 3 times $9 is $27? Wheres the 28th dollar?

The men paid £10 each, they got £1 back, that leaves £2

3 X 9 is 27 but they never paid that, they paid £10 each.

they got a $1 back out of the $10 they each paid which means $1 - $10 = $9.

-Guys paid 10 each so 3x10 = 30
-They got a 5 bucks refund so 30 - 5 of refunds = 25 bucks for the room.
-The lady had to give them the 5 bucks extra, which comes back to the
3 guys.
- On the 5 bucks that come back to them, she gives them 1$ each
- 3 X 1 dollar = 3 bucks
- So 5 bucks that should be refund - 3 bucks that have been refund = 2

Therefore: Maid kept 2 bucks
