The formula to calculate the HCF Cost (HCF) is:
\[ HCF = \frac{G \times CPG}{748.1} \]
Where:
Let's say the total gallons of water (G) is 1500 gallons and the cost per gallon of water (CPG) is $0.005. Using the formula:
\[ HCF = \frac{1500 \times 0.005}{748.1} \approx 0.01 \]
So, the HCF cost is approximately $0.01 per HCF.
