The Hydro water department has a monthly service charge of $11.60 and a volume charge of $2.17 for every 100 cubic feet of water.

The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 2.17x + 11.60

y = 2.17x + 11.60

If the Johnson family used 200 ft3 more water this month than last month, then they can expecta a.decrease in their water bill of $23.20.
