Answer 2

Why do you ask me to do it?

Answer 3

You were online.

Answer 4

There are many other potential helpers online as well.

Answer 5

I asked others as well. I just remembered you helping me before.

Answer 6

I see

Answer 7

So the first part asks you to determine the total number of points per player
with R=5 points, Y=10 points, B=15 points

So Julie gets 15R, 6Y, 2B
So she gets (15*5)+(6*10)+(2*25) points

Steve gets 17R, 3Y, 4B
so that equals (17*5)+(3*10)+(4*25) points

I'm not sure what form you are meant to put the matrix in, but personally, I would let
Red=X
Yellow =Y
Blue=Z

So the number of points won per colour is
\[\left[\begin{matrix}X & Y&Z \\ 5 & 10&25 \\\end{matrix}\right]\]
and then to put in term what they won
I would do
\[\left[\begin{matrix}X & Y&Z\\ 15 & 6&2\\ 17&3&4\end{matrix}\right]\]

I'm not sure if that is what it is asking, as I'm not familiar with this kind of question, but that is what I interpret it to be

Hope that's of some help
