A 400400

B −400−400

C 1,0001,000

D −1,000

The submarine is currently 700 feet below sea level. If it ascends 300 feet, its new position would be 700 - 300 = 400 feet below sea level.

So the integer that represents its new position is D) -400.

To find the submarine's new position, we need to add the ascended distance (300 feet) to its initial position (700 feet below sea level).

The new position can be calculated as:
Initial position + Ascended distance

So, the submarine's new position is:
700 + 300 = 1000

Therefore, the integer that represents its new position is 1000.

The correct answer is C. 1,000.
