Answer:
3.5gal/1week
Explanation:
First, you would want to find how much the storage container leaks in a day. You can do this by dividing 15 by 30. This answer will tell you how much it leaks in a day.
15 ÷ 13 = 0.5
Now, as you can see 0.5 gallons of water leak out of the container each day.
Next, you will then multiply how much leaks out in a day (0.5) by 7. This will get you your answer of 3.5.
Therefore, 3.5 gallons of water leak out of the container each week.
To check your work you can multiply how much water leaks out in a day by 30.
30*.5 = 15 gallons in 30 days.
I hope this helps you! :)
