The diver starts 15 feet below sea level, which is represented as -15 feet. When the diver swims up to the surface, they are moving up 15 feet, which can be represented as +15 feet.
So the correct mathematical expression to represent this situation is:
\[
(-15) + 15 = 0
\]
This indicates that starting from -15 feet and swimming up 15 feet brings the diver back to sea level (0 feet).
Therefore, the correct answer is **A. (-15) + 15 = 0**.
So the correct mathematical expression to represent this situation is:
\[
(-15) + 15 = 0
\]
This indicates that starting from -15 feet and swimming up 15 feet brings the diver back to sea level (0 feet).
Therefore, the correct answer is **A. (-15) + 15 = 0**.
