After the first hour, 200 gallons are left. Then 100. Then 50. After three hours, 50 gallons are left.

Ok you've got the rate now!
50 gallons are left
1st hour - 400/2 = 200
2nd hour - 200/2 = 100
3rd hour - 100/2 = 50
You can also figure it out by multiplying by 0.5

After one hour, there will be 200 gallons left. (400 divided by 2)
After two hours, there will be 100 gallons left. (200 Divided by 2)
So after three hours, there will be (100 Divided by 2) gallons left.
50 gallons of water.
And someone needs to fix that pool.

50 gallons.
1st hour: 400 - 200 = 200
2nd hour: 200 - 100 = 100
3rd hour: 100 - 50 = 50
Hope that this helps

The answer is "not enough information." You need to know how much water leaks out per hour, minute, second, or something. Your teacher will be impressed that you realize there is not enough information.

Depends on how much water it leaks per hour.

If it's leaking half of its water in one hour, after two hours it would be empty.
