Question

I WILL MARK BRAINLIEST!

Answer 1

First, let's get a clear visual of her weekly income:
Saturday hrs. of work = 6
Monday hrs. of work = 4
Dog walker salary per. week = $20
Weekly income = $130
We can rule out A, since it doesn't even include the amount of income she earns on Monday.
We can also rule out D, since it doesn't include the amount of income she earns on Saturday.
Lastly, we can rule out B, since it doesn't include the mount of income she earns while walking dogs.

Thanks to the rules of elimination, we can concur that the correct answer is C. It includes all components of income during Amy's week, formulating a strong equation to determine the value of h.

Hope this helps. :)

Answer 2

The answer is the third one 
-the hours are unknown so its 6+4h
the total is 130 and she earns an extra 20 dollars so
(6+4)h+20=130
