1. What is your water bill this month? $ ______ (A)
2. How many gallons of water consumed this month? _____ (B)
Note: Your monthly water bill (A) (divided by) your total gallons
of water consumed (B) will give you the cost of water per gallon ©
3. What is your sewage bill this month? $ _____ (D)

of water consumed (B) will give you the cost of your sewage per gallon (E)
5. What is your [(i) Electric / (ii) Gas] bill this month? $____ (G)
6. What is your [KwH / BTU] consumption this month? ______(H) ( example: 2.9 BTU = 2,900,000 )
* Question 5 and 6 will depend on the dropdown list chosen from question #4
Note: Your monthly kWh/BTU (i / ii) (divided by) your total kWh/BTU used will give you the cost of your kWH/BTU (I/J).
For Electricity (i):
- *It takes 0.13958 kWh to heat 1 gallon of water from 50F to 120F.
- The length of shower ( #11)(multiplied by) (Q or R) = The number of gallons used (K),
The number of gallons used (K) (multiplied by) 0.13958 kWh = How much it cost you to
heat the water for the length of your shower (L), (L) (multiply by) The cost of your kWh (I)
= What it would cost to heat the amount of gallons used in your shower (M).
For Gas (ii):
- *It takes 890 BTU’s to heat 1 gallon of water from 50F to 120F.
- The length of shower ( #11)(multiplied by) (Q or R) = The number of gallons used (N),
The number of gallons used (N) (multiplied by) 890 BTU = How much it cost you to heat
the water for the length of your shower (O), (O) (multiply by) The cost of your BTU (J) =
What it would cost to heat the amount of gallons used in your shower (P).
