Suppose that a households 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 1.55

if the monthly cost for 23 HCF is 49.90, what is the monthly cost for 17 HCF?

for 23 HCF is $49.90, what is the monthly cost To 49.90 Monthly cost (in dollars) 23 Water usage (in HCF)
