Question

Mark received a 3.5% salary increase. His salary after the raise was $36,432. What was his salary before the raise?

Answer 1

There's many way on how to find the answer to this problem.
One way is to write this type of equation:
Let x = Mark's original salary.
(3.5% * x) + x = 36,432
Now its not proper to write percent in an equation, so you can convert percent into decimal.
To convert 3.5% into decimal, then move the decimal 2 places to the left. So 3.5% in decimal would be 0.035.
So the equation would be: (0.035x) + x = 36,432.
Now solve for x. :)
I hope this help.
Also, if you want me to explain on how I got "(0.036x)", then just ask me. :)

Answer 2

"(0.035x)" My bad.
