My question is: Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat? Your thoughts:
They need 1600 square feet / 400 square feet / gallon = 4 gallons of paint for their walls. Since they will do a second coating, then they would need 4 gallons x 2 = 8 gallons in all. Eight gallons of paint will cost $45 / gallon x 8 gallons = $360. Thus, Jason and Jeremy will each contribute $360 / 2 = $180. The final answer: 180.
