Sara works 40 hours per week and earns $660. which graph shows the unit rate for this situation? a) a b) b c) c d) d

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.
