Set Y to the maximum number of remaining bananas, and X to the required vertex (x meters). The equation can be listed: 1. Y = (100-3x)-(50-x) = 50-2x, so the smaller the value of X, the larger the value of Y. 2. (100-3x) Y = 16 It is easy to find y = 16 Popularity: First, move 50 to 17 meters (a point), eat 17 and 33, and leave 16 at a point. Then, take
