For one quarter, a home owner's water bill was $9.38. The water company charges $6.50 for the first 1,200 cubic feet or less, and $0.40 per hundred for the next 3,600 cubic feet. How many cubic feet of water did the home owner use during that period?
Answer: 1,920 cubic feet
Here is my solution: What cubic feet * $0.40/100 cubic feet = ($9.38 - $6.50) + 1,200 cubic feet?
Is there a better solution than mine?
