Answer:
m = 9h
Explanation:
you can see that in 5 hours she earns 45 dollars
divide 5 hours by 5 and 45 dollars also by 5
you then find that in 1 hour she earns 9 dollars
so in h hours she earns 9 times h
which is h = 9h
but in this case it asks for money so it is m = 9h (h is how much hours she worked)
