We will evaluate each case separately:
with a roller:
P1 = (40/8) * 10 + (1/2) * 10 = 55 $
spray gun:
P2 = (40/20) * (5 + 10) + (1) * (10) = 40 $
Then, the saving is:
P1-P2 = 55-40 = 15 $
answer:
you save by using the spray gun on a paint job that involves painting 40 m2 15 $

Answer: x≠0 and x can not be any value for which u(x) = 2
Step-by-step explanation:
According to the question,
The domain of the function u = R - {0}
Thus if x is the element of the domain of the function u
Then , x ≠0
(v*u)(x) = v[u(x)]
Since, The domain of the function v = R - {2}
⇒ u(x) ≠ 2
⇒ Second Option is correct.
