Your salary after a 3% salary increase if your salary before the increase was S, what is the algebric expression?

S + 0.03S

To determine the salary after a 3% increase, you would multiply the original salary (S) by 1 plus the percentage increase (3% or 0.03). The algebraic expression for the new salary (N) would be:

N = S + (S * 0.03)

Alternatively, you can simplify it as:

N = S * 1.03

So, the algebraic expression for the new salary (N) after a 3% increase is N = S * 1.03.
