Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, HCF) When graphed, the function gives a line with a slope of 1.65 See the figure below It the monthly cost for 15 HOF 46.14, what is the monthly cost for 12 HCF?
