Answer:
18,152 Gallons
Explanation:
First, you'll want to put this into an equation. We'll use x as the amount of water in gallons that will remain in the pool.
18,968 - 12 (68) = x
First, we'll multiply - 12 and 68.
We'd end up with this:
18,968 - 816 = x
From here, we can just subtract 816 from 18,968.
18,152 = x
Now we can see that there will be 18,152 gallons of water left in the pool after 68 days.
