Now that Joe's firm has switched to the more expensive biodegradable disposable cups, the city where his firm operates decides to increase the cost of the annual business license fee from $1,000 to $5,000 to cover the salary of the newly created position of a biodegradable cup enforcement officer. Thus, Joe, who is about to pay his 2023 business license fee, will pay $4,000 more. (You do not have to show the specific magnitude of this change in your graph; creating curves that show the general impact of this change on costs will be sufficient.)
