A submarine was 200 yards below sea level. If it descends 48 yards further, what is the new depth of the submarine? Write a sum of integers to represent the situation.

• 200 + (-48) = 152; the submarine is 152 yards below sea level

• 200 + 48 = 152; the submarine is 152 yards above sea level

• 200 - 48 = 148; the submarine is 148 yards below sea level

• -200 + (-48) = -248; the submarine is 248 yards below sea level
