The city government is considering two tax proposals:

• A lump-sum tax of $300 on each producer of hamburgers.

• A tax of $1 per burger, paid by producers of hamburgers.

a. Which of the following curves—average fixed cost, average variable cost, average total cost, and marginal cost—would shift as a result of the lump-sum tax? Why? Show this in a graph. Label the graph as precisely as possible.

b. Which of these same four curves would shift as a result of the per-burger tax? Why?

Show this in a new graph. Label the graph as precisely as possible.
