29. 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. (figure shows a vertical line which show monthly cost in dollars and a horizontal line which shows water usage measured in HCF, the water usage is 20 and the dollar amount is 23.66)
If the monthly bill for 20 HCF is $23.66 , what is the monthly bill for 24 HCF?
