A painter is paid 10 dollars per hour and can paint 8 m2 with a roller in this time. renting a spray gun costs 5 dollars for eac

Slav-nsk [51]

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 $
