Final Exam Review Sheet
Winter 2017
The final exam covers Chapter 2, Sections 3.3 – 3.7, Sections 4.1 – 4.3, Chapter 5, Sections 6.1 - 6.4, 6.6 6.7, Chapter 7, Chapter 8, and Chapter 9.
Make sure you read all the directions on the final exam. You will have some choices on the problems that
you solve. For example, the directions for a group of problems may state “Do any 4 of the following 5
problems.”
You will have a problem from Section 9.6 that you must solve; the compound interest formulas will be
given, if needed.
