1 4. Elderly relatives have asked you to come paint three rooms inside their
home as they can no longer physically do it themselves. They have all of the
tools for the job but need you to get the paint. They will pay for all of the
paint needed and give you $100 extra for doing the job. The measurements
of three rooms are 9' x 10', 15' x15', and 10' x 12'. The wall height (or ceiling
height) is 9' tall. The paint costs $38.99 a gallon, that covers 350 square feet
per gallon. What is the amount of the check that elderly relatives will write
that will cover the cost of the paint plus your bonus money?
