Answer:
For Jerry, the opportunity cost of building a fence is not making 2 dishes.
Step-by-step explanation:
The opportunity cost refers to the benefit you lose when you choose one option over another one. In this case, the opportunity cost for Jerry when he decides to build fences is that he won't be able to make dishes. So, as he can build 7 fences or make 14 dishes in a day, the opportunity cost of building a fence is that he won't be able to make 2 dishes.
