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 1.75. See the figure below. If the monthly cost for 16 HCF is $46.68, what is the monthly cost for 12 HCF? Monthly cost. 46.68 (in dollars) I 1 16 Water usage S
