You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than 23 of the elevation of the entrance. What is the elevation of the entrance?

I'm assuming you meant 2/3. I have the same problem, and I'm not 100% sure why, but I checked it and it is correct.

I know BIM says it is incorrect, but the answer while doing it several ways is 21. I'm sorry this wasn't more helpful.
Oh! You just have to say it is -21 feet, because it is below sea level. Hope this helps. BIM took that answer, so yeah.
