Hi there!

Let the amount of hours Kim worked be represented by X.
Her total earnings on a Friday night can be expressed as $30 + ($1.25 × the amount of hours). We can now set up a function for her total revenue (represented by Y).


When Kim works 3 hours we need to plug in x = 3 into the formula.



Therefore, after 3 hours of working, Kim would have made $33.75
