a.Identify the range of output exhibiting increasing returns (increasing MP), and the range exhibiting diminishing returns (decreasing MP).

b.Current fixed costs for the company equal $102,500. Draw two graphs, both with Q on the horizontal axis: one graph shows TVC and TC, and the other shows AVC, AC, and MC.

c.Suppose that the government imposes a $32,000 property tax hike on all businesses; how will that affect your two graphs; i.e., which cost curves will be affected and how?

d.Suppose instead that the government considers your production process to be polluting, and imposes a $710 tax per unit produced (replacing the property tax in the previous question). How does this tax increase compare to the property tax increase, in terms of the effect on your company's cost curves?
