s < 30,000$ i dont know if this is what the question is asking but its the best i can come up with given the information you gave to me.
I think you could multiply or divide. Hope this helps:)
There are no shaded regions below so we cannot find the value of these things
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
