the diver started 65 feet above the water and ended up 15 feet below the surface. Can you answer what is the change in elevation?

15. Selena2345

No i can't answer the change in the elevation. It is hard for me.

when you hear the word "change" you should subtract... which reminds me, i need to change the picture a bit...
