Answer:
$15 per hour
Step-by-step explanation:
Well, let's call her unknown hours for h.
We know her total price is 270, and the she works a total of 18 hours.
Now let's put this into an equation:
270 = 18h
Now we just have to isolate h to find the amount of hours, so you divide by 18 on both sides:
H = $15
