Question 5 Let's return to the apples and bananas from Question 1.

Take your answer to Question 1 and convert the system to echelon form. I. e.,

[1A12′A13′01A23′001][abc]=[s1′s2′s3 ′]
1A12′A13′01A23′001
abc
=
s1′s2′s3′
⎣⎢⎡100A12′10A13′A23′1⎦⎥⎤⎣⎢⎡abc⎦⎥⎤=⎣ ⎢⎡s1′s2′s3′⎦⎥⎤.

Find values for A′\mathrm{A}'A′ and s′\mathbf{s}'s′.
