You make $ 90000 a year, and you get a 10% raise. Your new salary is $ .???
The next year you get a 10% cut. Your new salary is $ ????. That is ??? % less than your initial salary.
How would I go about solving this??

What is 10% of $90,000? Add that to $90,000 to find your salary after the raise.
What is %10 of the new larger salary?
Substract that to find what your salary is after the %10 cut. 
Retyping last lines...
What is 10% of the new larger salary?
Subtract that to find what your salary is after the 10% cut.
