Answer:
-35.25 - 8.5 = -40.75 meters
Step-by-step explanation:
When talking about a submersion depth of -32.25 meters, that means the submarine has dropped 32.25 meters.
If we add 8.5 meters of additional submersion to that value, we get:
-32.25 meters + (-8.5 meters) = -32.25 meters - 8.5 meters = -40.75 meters.
