If Navya babysits 12 hours she earns $48. If she babysits 18 hours she earns $72. Let y represent the total amount of money that Navya earns working x number of hours.
I think it’s 4 dollars bc 48%12 is 4 and it’s consistent. It doesn’t matter how many hours she works she will still get the same 4 dollars an hour.
