PLEASE HELP ASAPPP!!!!!!The elevation of city A is 96 feet below sea level; the elevation of city C is 24 feet below sea level.

goblinko [34]

So we know that:
City A is -96ft in elevation
City C is -24ft in elevation
City D is (1/4C)ft in elevation.
So, knowing this we can make an equation: 1/4•-24/1=-24/4=-6
So from that, we get the result of City D being -6ft in elevation, or 6ft below sea level.
