The deck of a ship is 7 feet above the surface of the water. There is
also a cabin that is 14 feet below the deck. Which number describes
the elevation of the cabin?
Note: Your answer is expected to be a number without units for this
problem
-7 feet because 0 is water level and the deck of the ship is 7 feet above eatet and the cabin is 14 feet below the deck so you subtract 14 from 7 and get -7 (7-14=-7)
