Things that should receive credit
   1. #3 if you put income decreases and luxury good. A luxury good is a normal good and will generate the right movement.
   2. #5 tax can be shown by using any of 3 ways we talked about it class provided you did the analysis correctly. 
   3. ignore all comments about needing to use solid or dotted lines--I don't think points were taken off for that.

Suggestions
   1. Learn differences between change in D and movement along D; change in S and movement along S.
   2. elasticity = 1/slope x p/q. Calculate the right slope: y = mx + b or p = mQ + b
   3. Make sure that within an answer sections are consistent with other sections. For example, on #1, some people had a) Q decrease; b) Q increase; c) Q decrease. This happened in other problems, too. Make sure equations are consistent with words and words consistent with figures.
   4. Label graph means to label all prices (p, pc, ps, p control) and quantities (q, qd, qs, q control, shortage, or excess supply)


Ask two questions:
    1. What did I miss?
    2. Why did I miss the question?
