Answer:

225 feet below sea level (or -225 feet)

Step-by-step explanation:

My apologies in advance if this does not format the way its supposed to. The way I did it includes arrows and may work best on a computer.

Problem: A submarine that is 245 feet below sea level descends 83 feet and then ascends 103 feet. Which represents the location of the submarine compared to sea level.

Math: Ok, so we know that whenever something descends, that means it is going down, so let's use a negative sign. These means when something ascends, it goes up. Let's use a positive sign here. Also, note the fact that we start 245 feet below sea level. This means we should start at -245.

Now, using the data we have, let's create a math problem.

A submarine that is 245 feet below sea level descends 83 feet and then ascends 103 feet. Which represents the location of the submarine compared to sea level.

-245      <---- beginning level

-83        <---- the submarine descends

+103      <---- the submarine ascends

_______

?

So grab a calculator to do this part, or do it on your own. Once you finish, plug in the answer.

-245                                                   -245

-83                                                     -83

+103                             --------------->  +103

______                                          ________

?                                                      -225 feet

So as you can see, the final answer would be -225 feet or 225 feet below sea level.

Hope this helped! Have a great day!
