Set up a proportion in the form of:
percent%2F100+=+part%2Fwhole

"percent" basically means PER 100.
Our percent here is 6.
Our "whole" here is 50,880.
We do not know what our part is. This will be "x"
Let "x" represent the increase of the amount she made from last year.

6%2F100+=+x%2F50%2C880

Cross multiply 6*50,880 which is 305,280.
Divide by 100 to get "x".
This year, she is making $3,052.80 more than last year.
To get what she made last year, subtract the increase from 50,880.
50,880 - 3,052.80 = 47827.20
She made $47,827.20 last year.
