Question

The water level in the aquarium’s shark tank is always greater than 25 feet.

If the water level decreased by 6 feet during cleaning, what was the water
level before the cleaners took out any water?

Answer 1

If the water level is always at 25 feet or above, than you would add 6 feet to this in order to represent what the water level would be above before the cleaning.

The water was over 31 feet before the cleaners removed the water.
