New salary = $20.01/hr = x + 0.0475x + 0.0325x, where x represents the original hourly wage.
20.01 = x(1 + 0.0475 + 0.0325), or
20.01 = x(1.08). Therefore, x = 20.01 / 1.08 = 18.53.
Her initial hourly wage was $18.53.
Call the old salary x.
20.01 = x + .0475 x + .0325 x
We factor out x and add up the coefficients:
20.01 = 1.08 x
Now we solve for x by dividing both sides by 1.08
x = 20.01/1.08 = $18.53
Answer: $18.53 per hour
Check: 18.53(1+.0475+.0325)=20.0124 good
