The extra dollar never existed.

The original amount is $30.
The room is $25.
The 'pocketed amount' is $2.
The refunded amount is $3.

$9 x 3 = $27

The amount the Clerk pockets is within the $9 paid, the $3 given back makes the total up to $30, the $2 is deducted from the $27 not added to make the $25 room cost.

Quoting Rufruf (Reply 4):
It's all in interpretation. Logic ? maybe. numbers don't lie ............ right

Actually, in the puzzle given in your original post, numbers do lie.

You say that the three people get $1 each back, and the motel clerk pockets $2.

Then you say that $10 - $1 = $9. Thats reasonable enough.

However, in that $9 is a cut of the $2 the Clerk keeps, so to add it on later ($27 + $2 = $29) is wrong because its already counted in the running total. What should be added on is the three $1 refunds, which takes the total up to $30 as expected.

Nothings missing, the puzzle as given is basically incorrect on purpose in order to provide the problem stated.

The real question is - what are three people doing with a motel room together? Why havent I been invited?

It's a trick with the wording.

Richard pretty much explaind it, but to add to it, the three really paid £0.66 each I think of the new amount to contribute to the extra them gave away.

Quoting CastleIsland (Reply 9): All I can say is that this sounds like an "hourly rate" at a sleazy motel in a bad part of town.

We spent a whole period in economics talking about this problem...

A guy asks 'What's Punk?'. I kick over a trash can and its punk. He knocks over a trash can and its trendy.

The coefficient of x^3 is zero since sin 0 = 0 thus the answer stops there.

Pretty simple if you ask me, it's just substituting values into equations. Requires no brains!

My bad, the answer should be 3 - 13.5x^2. Not 15.5 as I said above. I did my A Levels in 2000 which was the last time I touched Maclaurin's series. Thankfully I still remember calculus though I've clearly forgotten how to do simple division. 27/2 is indeed 13.5 and not 15.5.
