He knows he is going to be asked to make even change so he simply pockets 2 of the $1 bills. (More honest than just skipping with the entire $5 in change.)
He then hands each woman 1 - $1 bill. Each woman's portion of the meal was now $10 minus $1 equaling $9 or $27 total. He has 2 - $1 bills in his pocket. $27 plus $2 = $29.
Question: Where did the other $1 go?
This is why I8math.

It's a trick question. The last paragraph says they each paid $9 totaling $27. We don't care about that. The women each got three dollars and the waiter got $25 + $2 = $27
$27 + $3 change = $30.
That's not algebra, that's critical thinking skills. Took me about 5 minutes to figure it out... I hate that kind of treachery.
Algebra is not evil or hard. I am biased because I went into engineering though...
The two hardest subjects for me are electrical wiring and biology / chemistry...
