Final answer:
To lay out your warehouse optimally, place the most frequently sold items closest to the dock.
Step-by-step explanation:
To lay out your warehouse optimally, you need to minimize the distance you have to travel to the room farthest from the dock. One way to do this is by placing the most frequently sold items closest to the dock. In this case, since you sell 11 red bottles per day, 27 green bottles per day, and 49 yellow bottles per day, you should place the yellow bottles closest to the dock, followed by the green bottles, and then the red bottles. This way, you will have to go to the room farthest from the dock only once per day.
