What is the total weight change from the four modifications?

Explanation:
Total weight change is found by adding the weight changes from each modification, using signs: positive adds weight, negative removes weight. You must sum all four changes to get the net effect on the aircraft’s weight. In this problem, the four modifications together result in a net increase of 41 pounds, so the total weight change is +41 pounds. That’s why this option is the best answer. (For intuition, you can think of combining four numbers with their signs until you reach the final sum; any other total would mean a different combination of the four changes.)
