Answer:
i dont think you can solve this because
The expression is not factorable with rational numbers.
there are no like terms
I would pick 750 - 250 because that equals 500. You can also prefer using 800 - 250.
The perpendicular gradient to that would be 1/3x
So y= 1/3x + 4.5
Step-by-step answer:
Given:
Initial monthly salary = $5000
New salary = 10% less
Salary a year after = 15% more
Solution:
New salary
= 5000 * (100-10)%
= 5000 * 90%
= 5000 * 90/100
= 4500
Salary a year after
= 4500 * (100+15%)
= 4500 * 115%
= 4500 * 115/100
= 45*115
= 5175
