Question

A scuba diver went down 20 feet below the surface of the water. Then she drove down 3 more feet. Later, she rose 7 feet. What integer describes her depth?

Answer 1

Ok. So what you want to do is -20 because it says went down 20 ft. Then -3 more. + 7. -20+-3=-23+-7=16 So you get 16. I hope that helps.
