Math Riddle

[Lemon Zinger]

Three colleagues are on a business trip when their car breaks down. Fortunately, they are in a town and just go to an inn. They decide to share a room and split the bill. A room costs $30 and so each pay $10.

The next morning, the manager realizes he overcharged them because it was discount Tuesday. The room was only $25 that night and so he sent his assistant over with the extra five dollars.

The men, deciding to be fair, each took back a dollar and gave the other two to the assistant as cash. So each man paid 10, but got a dollar back so they only paid 9.

9x3=27 + 2 (the assistant's)=29. Where's the other dollar?

I see what I did wrong, let me solve it the right way... ><

Flameh beat me to it. xD So instead of posting a formula myself, look at hers. (:

There was $25 for the room
$1 for each of the colleagues = 1x3
$2 for the assistant

25+(1x3)+2= 30
