For the answer to this question, let us assume based on the 40 hours per week that she's working 8 hours a day and 5 days a week. first, you must divide 660 by 40 hours to see how much she earns per day. 660/40
now we know that she earns $16.5 per day. I hope my answer helped you.
Since she works 8 hours a day and 5 days a week,you must would 660 by 40 hours to see how much she earns per day and simplify ur answer. giving up 16.5 :]
