Answer 1

Answer:

Step-by-step explanation:

First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.

60 / 4 = 15

Now we divide their total of $210 by their hourly rate of $15 to find how many hours it would take.

210 / 15 = 14

I would take 14 hours to earn $210.
