Responses

A. (−15)+(−15)=−30

B. (−15)+(−15)=0

C. (−15)+15=30

D. (−15)+15=0

Answer 1

The correct expression to represent the diver swimming from 15 feet below sea level up to the surface is:

D. (−15) + 15 = 0

This shows that starting at -15 feet (below sea level) and swimming up 15 feet brings the diver to sea level (0 feet).
