  1. Calculate total water usage: Calculate the total water usage for the month.\newlineTotal water usage = Number of people ×\times Average water usage per person\newline= 6×726 \times 72 liters\newline= 432432 liters
  2. Calculate total cost: Calculate the total cost for the water used.\newlineTotal cost = Total water usage ×\times Cost per liter\newline= 432432 liters ×\times $0.20\$0.20/liter\newline= $86.4\$86.4
  3. Calculate total shower time: Calculate the total shower time for the month.\newlineTotal shower time == Number of people ×\times Average shower time per person\newline=6×480= 6 \times 480 minutes\newline=2880= 2880 minutes
  4. Calculate cost per minute: Calculate the cost per minute of shower water.\newlineCost per minute = Total cost / Total shower time\newline= $86.4\$86.4 / 28802880 minutes\newline= $0.03\$0.03 per minute
