The amount of money the Trevor's family pay per minute on shower water is $0.03

How to find cost of water per minute

  • Total number of people in Trevor's house = 6

  • Number of bathrooms = 3

  • Time each person spent bathing = 480 minutes

  • Water used by each person per month = 72 liters

  • Cost of water per liter = $0.20

Cost of water used per minute = Water used by each person per month / Time each person spent bathing × Cost of water per liter

= 72 / 480 × 0.20

= 0.15 × 0.20

= $0.03
