Answer:
a.
Step-by-step explanation:
Usually, we represent losses with negative numbers. Using that representation, a loss of $975 would be represented by the integer -975.
__
The additive inverse of this number is also called its "opposite." It is found by changing the sign: additive inverse = +975.
__
The sum of a number and its additive inverse is zero. The opposite of a loss is a gain. The value +975 represents the gain (the investment's earnings) that would bring the net change in investment value back to zero.
