Answer 1

First, the pool was filled to 3/4 of its capacity, which is equal to:

`24000\cdot(3)/(4)gal=18000gal.`

Then, 1/9 of the water evaporated remaining 8/9 of the 18000 gal:

`18000\text{gal}(8)/(9)=16000gal.`

Therefore, to fill the pool we need to add:

`24000-16000`

gallons of water.

Answer: B. 8000.
