Residents of your city are charged a fixed weekly fee of $6 for garbage collection. They are allowed to put out as many cans as they wish. The average household disposes of three cans of garbage per week under this plan. Now suppose that your city changes to a "tag" system. Each can of refuse to be collected must have a tag affixed to it. The tags cost $2 each and are not reusable.

a)What effect do you think the introduction of the tag system will have on the total quantity of garbage collected in your city? Diminish or increase?

b) Briefly explain your answer.
