Explanation: Here are two forces applied in opposite ends of the rope, both forces pulling the rope in one direction (opposite directions).
this means that the total force is the addition of the two forces (not exactly, because they are at different heights, but is a good approximation), the resultant force will be 175N - 75N = 100N
Here you can see that the force pulling right is almost 100N bigger than the other force, this means that factors like the difference in height actually don't matter, the difference in force is large enough to predict that the net force on the rope moves it to the right.
The correct answer is total revenue minus total cost.
When a firm is calculating the profit they need to find the difference between how much money they earned and how much they spent. The difference between their total revenue and their total cost is their profit.
