Final answer:
To find the weight of the apple, subtract the weight of the boxes from the total weight. The weight of the apple is 1918.6 pounds (option C).
Step-by-step explanation:
To find the weight of the apple, we need to subtract the weight of the four boxes from the total weight. The four boxes weigh a total of 56 pounds. One box weighs 25.4 pounds. So, the total weight of the boxes is 56 + 25.4 = 81.4 pounds. Subtracting this from the total weight of 2000 pounds gives us the weight of the apple, which is 2000 - 81.4 = 1918.6 pounds. Therefore, the weight of the apple is 1918.6 pounds (option C).
