Answer:
1.33 walls
Explanation:
Here is the complete question :
Amy and Bill are fixing up their house by painting walls and installing electrical outlets. In one hour, Amy can paint 8 walls, or install 6 outlets. In one hour, Bill can paint 5 walls, or install 5 outlets a. If Amy painted 8 walls in the first hour of work, and then switched to doing 6 outlets in the second hour of work, what was the opportunity cost of each of those outlets?
Opportunity cost is the cost of the next best option forgone when one alternative is chosen over other alternatives.
By doing the outlet, Amy is forgoing the option of painting walls.
Opportunity cost = 8/6 = 1.33 walls
