Each gallon of paint coss $20 and covers 350 square feet. Find the total cost to paint this side once. Justify your answer. (hint the total square feet to find is 604.2)
Area needed to paint= 604.2 / 350 = 1.726 gallons . For 0.726 say 1 gallon therefore the total cost for two gallons would be $40. If you could buy 0.726 gallons'cost will be 1.726*20 = $34.52.
