Suppose a deep sea diver dives from the surface to 250 feet below the surface. He then dives down 15 more feet. Use integers to represent this situation and then find the diver's final depth.
First dive = -250 ft;
Final depth = -235 ft;
First dive = 250 ft;
Final depth = 265 ft;
First dive = -250 ft;
Final depth = -265 ft;
First dive = 250 ft;
Final depth = 235 ft.
