Answer:
11508 liters
Step-by-step explanation:
The Faruq family uses 548 liters of water per day. The Chammas family uses 3 times as much water per day. How much water does the Chammas family use per week?
Solution:
The amount of water used by the Chammas family is three times that of the Faruq family per day, hence:
Amount of water used by Chammas family in a day = 3 * water used by Faruq family in a day
Amount of water used by Chammas family in a day = 3 * 548 = 1644 liters
The amount of water used by the Chammas family in a week = 1644 liters per day * 7 days in a week = 11508 liters
Therefore 11508 liters of water was used by the Chammas family in a week
