Answer:
The cost incurred by Trevor's family per minute on shower water totals $0.005.
Step-by-step explanation:
The price of water is:
Cost = $0.20/liter
Water consumption over the past month:
Amount of water used = 72 liters
To calculate the total water expense:
Total water cost = Amount of water used × Cost
= 72 × 0.20
= $14.4/liter
The average time each individual spent showering is:
Average number of minutes = 480 minutes.
Total individuals in Trevor's household:
N = 6
Calculate the total shower duration for all 6 individuals:
Total amount of time = Average number of minutes × N
= 480 × 6
= 2880 minutes
Calculate the cost per minute for shower water:
Pay per minute on water = Total water cost ÷ Total amount of time
= $14.4 ÷ 2880
= $0.005
Therefore, Trevor's family pays $0.005 per minute for shower water.
