8 dollars per hour is her pay when she has started the job. (equation given in explanation)

Explanation:

This is a simple question which required us to calculate pay per hour of Brianna when she had started the job. The current pay per hour is mentioned in the question and rate of change that is three times is also given.

So her past pay can easily be calculated with the help of simple mathematics equation given below.

Let suppose X is her pay to be determined. so

 X*3 = 24

(Means current pay is 3 times more than the initial pay)

Solving this we get 8 $ per hour (X=24/3)
