Now that each of the guests has been given $1 back, each has paid $9, bringing the total paid to $27. The bellhop has $2. If the guests originally handed over $30, what happened to the remaining $1?
I thought each guest paid $8 and 1/3 of the 25-dollar bill, so one more dollar would be $9 and 1/3, and if you multiply that by 3, then that would be $28. The bellhop has the other two bucks. I dunno how a dollar can be split into an exact one-third 8)

It's a trick question. Read it closer :)
The "extra dollar" only happens if you didn't follow it all correctly :wink:

<S.Yagawa> I like the challenge of "doing the impossible" with older hardware, and pushing it as far as it can go.

Hahah. The totals changed from 30 to 25! The guests paid 27 bucks for a 25-dollar tab - the extra two dollars were taken by the bellboy 8)

xbl0x180 alreqady said it; it's a trick question. Initially $30 were paid. $25 were kept by the hotel, $2 were kept by the bellhop, $3 were returend to the customers. The guests thus paid a total of $27 ($25 + $2 which the bellhop kept). The question makes it seem like in the end there were $27 PLUS $2, while in reality the $2 dollars the bellhop kept came out of those $27. Makes sense now?

First question on page 7.


Hmmm, I'll look that over. Thanks, Sapz.
The cowboy's back again!

Yup, I am currently taking up algebra in my college degree. I may actually sole some certain problems here. I got 1 and 2 so far.

Once I got to the first quarter of Physical Chemistry that goes into quantum physics, I had to take a coupla stiff drinks before I jumped in and attempted to solve some of this crap:

Thermodynamics completely lost me and I had to repeat the whole f*****g thing. That s*** felt like the Mushihimesama Futari and DFK true bosses combined. I suggest studying the kind of math wall street uses since the bankers never seem to lose :evil:

Oh, I cruised controlled and crashed right through that P-chem thermo final with a "C" and never came back. I was a little better with Organic Chemistry and Inorganic Chemistry since they're visual-based. Seriously, if you can put together that crappy IKEA furniture using their instructional picture diagrams, then you can do O- and I-chem. Rather than calculating the probability of finding an electron in the cloud, you are drawing the cloud itself or modeling the shape of the compound 8)

Hahaha. Funny, Dr. Meyer pops up if you do a general chemistry search. Cool dude 8)

A co-worker showed me a great resource today: http://ocw.mit.edu/courses/physics


Self education, here I come.
