1-C; 2-A; 3-D; 4-A (same as prob. 2); 5-A; 6-D;
7-B; 8-B; 9-B; 10-B; 11-D;
12-D; 13-A;
14-B; 15-D; 16-C; 17-A;
18-A; 19-C; 20-D; 21-B; 22-B; 23-C; 24-A; 25-A;
26-B; 27-A; 28-C; 29-B;
*30-B; 31-B; 32-D 33-A; 34-D;
35-B; 36-D; 37-C; 38-B;

*The table on this page 7 says it is for problems 7 through 11. Clearly the table is for problems 30-34.

**50 & 52 use some terminology that we did not discuss in class. The concept of economic surplus and deadweight loss are discussed in a section of chapter 4, I think, that we skipped over. You will not be responsible for this terminology. But a quick read might be insightful when it comes to efficiency.
