Answer 2

Answer: She wins $20.19 per hour.

Step-by-step explanation:

Here we have two points of data.

in 12 hours of work, she had $525.40

in 25 hours of work, she had $788.00

If we want to see how much she gets paid per hour, we need to find the slope of the linear equation, we can do this by the next equation

s = (Y2 - Y1)/(X2 - X1) where Y2 = f(X2) and Y1 = f(X1) for a linear function f.

In this case, we have:

s = ($788 - $525.50)/(25 - 12) = $20.19

So she wins $20.19 dollars per hour, the initial savings is bigger than 12*$20.19 because she may have previous savings, from before she started this new work.
