Lets say the 3x3 Matrix is
M = [1 5 2 ]
[1 1 7 ]
[0 -3 7 ]
We apply the Gauss-Jordan elimination method
(Procedure and result shown in the image below)
The man’s original salary was 100%. when increased by 10% , it becomes 110% which is $154 000.
so,
110% -> 154 000
1% -> $1400
100% -> $1400 x 100
= $140 000
