Almost positive this answer is the amount of hours she would work. because if she worked more hours her outcome would be a larger paycheck and if she worked less hours her paycheck would be smaller.
To find the inverse all you do is swap your x and y then solve it through. for this one you gotta take f(x) and make it y
y = 1/4x - 12
then swap
x = 1/4y - 12
then solve it through
x - 12 = 1/4y
divide by (1/4)
and (x - 12)4 = y should be your answer
