Question

The house Trevor's family lives in has 6 people (including Trevor) and 3 bathrooms. In the past month, each person showered for an average of 480 minutes and used an average 72 liters of shower water (over the entire month). Water costs 0.20 dollars per liter. How much money did Trevor's family spend, in total, on shower water in the past month?

Answer 1

Trevor's family spent a total of $86.40 on shower water for the month, calculated by multiplying the total liters of water used by the cost per liter.

Step-by-step explanation:

To calculate how much money Trevor's family spent on shower water, we need to multiply the total water usage by the cost per liter. Each of the 6 people in Trevor's family used an average of 72 liters of shower water over the entire month, and water costs $0.20 per liter.

1. Multiply the amount of water used per person by the number of people: 72 liters/person × 6 people = 432 liters.
2. Multiply the total water usage by the cost per liter: 432 liters × $0.20/liter = $86.40.

Therefore, Trevor's family spent $86.40 on shower water for the month.
