X - 10 = 25
add 10 to both sides
X = 35
Answer:
it 152.3
Step-by-step explanation:
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.
