can someone please help me answer this correctly someone gave me the answer 25 and that's not correct.

Answer:
A little more respect would go a long way.
Step-by-step explanation:
Be lucky some one gave you an answer most people don't get answers
ANSWER Negative 25 (-25)
The answer is correct, it is in fact 25 however it should be negative because we are under surface. -10+-15 is -25. SO you are -25 feet under water.
Hope this helps & good luck.
