Pls Help! Fan and Medal! The Hydro water department has a monthly service charge of $11.60 and a volume charge of $2.20 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 = 2.2x + 11.60 If the Johnson family used 300 ft3 more water this month than last month, then they can expect A. a decrease in their water bill of $6.60. B. a decrease in their water bill of $34.80. C. an increase in their water bill of $34.80. D. an increase in their water bill of $6.60.
