Answer:
6 liters per day
Explanation:
Hi there!
We know that Sarah drinks 30 liters on weekdays. There are 5 days in a week not including the weekends. You have to divide 30 liters by 5 to get the per day amount. 30 divided by 5 is 6. This means that Sarah drinks 6 liters per day. This is accurate because when you go on to check the amount of water she drinks on weekends, you know there are two days in a weekend, and you know she drinks a total of 12 liters during the weekend, so 6 liters multiplied by those two days is equal to 12.
Really hope this helps :)
