Assume all walls are 8 feet tall except the garage, which has 10 foot walls. If it costs 25 cents ($0.25) per square foot to paint walls, calculate the total cost to paint the walls for the following: 1 room 21`X 25`: 1 room 18` x 18`: 3 rooms 12` x 15`: Garage 23` x 28`: Leave off 1 23` wall for doors.
