d) 10 numbers on a phone keypad    (???)
l) 3 little pigs and the big bad wolf

I know, but I don't know how we could have helped her without seeing the puzzle...

do you mean that it is just one blank 9 x 9 square?...

If so, you could just rotate the numbers:
1,2,3,4,5,6,7,8,9
2,3,4,5,6,7,8,9,1
3,4,5,6,7,8,9,1,2
4,5,6,7,8,9,1,2,3
etc...

LOL...

And Irspow, that website was very interesting...how long did it take you to become comfortable with that system?

We may not teach it in schools because it is not really a universal way that people learn things (that's not to say that any one universal way even exists)...For example, it is easier for me to just memorize a phone number than it would be for me to memorize a sequence of words that represent the number in my mind...

I'm a pick-up truck kind of girl, in real life...

But from your list, I have to say that the Shelby is a lovely car...

I'm not sure if I am answering your question correctly because I don't understand what the company-wide sales has to do with it...But based solely on your sales at Store 1:

In 2003, Store 1 made 354% of the previous year (254% increase), in 2004, a 51% increase and in 2005, a 10% increase...
So from 2002-05, it looks like a total increase of 491%...

But this is mainly due to the huge increases you saw in 2003.  It appears as though they are leveling off, but I do not really know how to predict what to expect in the next three years.  Probably 0-10% on the previous year.

OMG that was too funny....
I'm going to be saying that all day...

Anyhow, Mikau you seem to be a very personable, bright young man...It is unfortunate that you feel as though your personal relationships are a disaster...Have faith (I do!) that you will be able to establish some relationships with people who can appreciate your interests, even if they do not share them...

What Are The Shapes That They Are Asking About?

Here's what I've got:

Max:  .2s + .25m     (OBJECTIVE FUNCTION)

subject to: (CONSTRAINTS)

s + m ≤ 70
s ≤ 50
m ≤ 30
s,m ≥ 0

Then, it sounds like you are using the Corner Point Theorem (I am assuming, since you asked for vertices).  So you would just graph the above constraints to find the feasible region, and then evaluate the objective function at each of the corner points:

Corner points (Vertices):
a = (0,0)
b = (50,0)
c = (0,30)
d = (40,30)
e = (50,20)

So evaluating your objective function at all of these points yields a maximum profit at corner point d=(40,30):

Max (C?) = $15.50 per day
with Snickers=40 and M&Ms=30

I hope that made sense....let me know if anything is unclear.

probably....if you listen to click and clack

I don't think that you stated it explicitly, (and it is probably sort of obvious) but you MUST, first and foremost, have closure under the operation for any kind of group to exist....

flatulant 13 year old...did that make sense?
And where are you that you are learning group theory in middle school!? 

looks okay to me...:)
