jeffs water bill includes a base charge of 12.00. plus a charge of 1.50 for each 1000 gallons of water used. his water bill is 28.50. how many gallons of water did jeff use?
ok u have to subtract 28.50 from 12 that is 16.50 and then u divide it by 1.50 then multiply the dividend that's your answer. I belive its 11,000 gallons.
