A. The Total Revenue function ios on Test 1 and Test 2. But now, on Test 2, it has two very different shapes. It might rise, max out, and fall back to zero like it did on Test 1. It might be a linear ray rising from the origin and out to the right, seemingly forever. It seems impossible that the same function could have such different shapes.Explain why this is possible.

B. In the inflation analysis project paired with this exam, I required the use of the XY scatter function in Excel instead of the line function.Why is this important when your dataset has some missing years?

D. In Classical Economics there are three dominant models of how firms act. These are pure competition, monopoly, and monopolist competition. While these models are mathematically elegant, a small group of economists object to them. In particular, they object to how the entrepreneur is handled in each of the dominant models. Briefly, what is their objection?

E. Using the trade accounts, why is a Current Account deficit and a Capital Account surplus two ways of looking at the same thing?

F. While this question seems different from the one above, they are about the same thing.Assume the U.S. economy falls into a deep recession. The rest of the world's economies continued with modest growth. Why would the U.S. Current account balance improve while the Capital Account balance would shrink?
