the salary after the 10% raise is equal to 45112.
if you let x = the salary before the 10%, then x + .10 * x = 1.10 * x is the salary after the 10% raise.
therefore, 1.10 * x = 45112.
solve for x to get x = 45112 / 1.10 = 41010.90909.
that's the salary before the 10% raise.
add 10% of 41010.90909 to it to get 41010.90909 + 4,101.090909 which results in 45112.
the salary after the 10% raise is 45112.
the salary before the 10% raise is 41010.90909
