The bill consisted of a fixed charge of $13.50 plus a charge of $0.0075 per gallon for the water used in the quarter. Let
G = number of gallons Judy used
So, we can write:
TOTAL BILL = $13.50 + ($0.0075)(G)Judy was charged $40.50, so we can write: $40.50 = $13.50 + ($0.0075)(G)
Subtract $13.50 from both sides to get: $27 = ($0.0075)(G)
Solve: G = 27/0.0075 = 3600
Answer: 3600
