The 10th ed. of textbook added a new section 21.3 Effective Rate and APY. This material was included in section 21.2 Geometric Growth and Compound Interest of the 9th ed. and all material is coverd in 21.2 videos and lecture notes. The 10th ed. of the textbook split the material on Present Value between sections 21.5 10th ed. A Model for Savings and 21.6 10th ed. Inflation. This material is coverd in 21.5 videos and lecture notes.

## Chapter 21 Objectives (Skills)

## Textbook Homework Problems (Practice/Not Graded)

The 9th or 10th edition of the textbook can be used for this course. All material covered is the same and independent of textbook editions. Homework problems between editions are the same.
 9th ed. 3, 11, 13, 25, 26, 40, 53, 54, 55, 56 pages 795 - 800 10th ed. 3, 6, 21, 31, 32, 46, 59, 60, 61, 62 pages 899 - 904

## Chapter worksheets (Sakai -> Assignments)

• Due by 11:55 pm Monday Dec. 4.
• Use the Assignments tool within Sakai to submit worksheet.

## Discussion Topic (Sakai-> Forums)

You will be required to participate in the discussion groups, i.e. Forums. The forums are aligned with the Learning Outcomes to provide practice and feedback and assessment for outcomes 3 and 4.

• Should you stock up on “forever” stamps? In 2007 the U.S. Postal Service began selling such stamps, which will suffice for first-class postage at any time in the future, even when rates rise. On Jan. 22, 2017 the U.S. Postal Service increased the price of these stamps to \$0.49. Would it be a good investment to buy a “lifetime supply” of them? To render your judgment, compare the historic increases postal rates (see http://www.vaughns-1-pagers.com/economics/postal-rates.htm) with the CPI Table in your textbook. For example, you could convert postal rates at each of the dates of change to the cost in today's dollars, then see if there appears to be a recent trend that you can project into the future.
• Discussion for Chapter 21 will open at 12:00 am Nov. 20
• You are required to participate in the discussion boards.
• Discussion topic will end at 11:55 pm Dec. 11.
• See the syllabus on the grading rubric for discussions.

## Student Resources (Publisher)

Math Applets and suggested websites are very helpful resources.

## URI General Education Course

General Education program 2016 (GE): This course fully satisfies both the general education Knowledge area A1: Scientific, Technology, Engineering, and Mathematical Disciplines (STEM) and Competency area B3: Mathematical, Statistical, or Computational Strategies (MSC).
General education program 2001 - 2015 (MQ): This course satisfies the general education requirement for Mathematical and Quantitative Reasoning.

## Course Description

LEC: (3 crs.) Introduces students to the spirit of mathematics and its applications. Emphasis is on development of reasoning ability as well as manipulative techniques. (Lec. 3/Online) Not open to students with credit in MTH 106 or MTH 109 and not for major credit in mathematics. (MQ)/(GE)

## Course Goals

The goal of this course is to prepare you for the mathematical and analytical aspects of the world around you, and to help you develop a stronger, deeper mathematical knowledge. This course is intended for students majoring in the liberal arts or other fields that do not have a specific mathematical requirement.

There is help available from the Academic Enhancement Center (AEC). The AEC offers three types of help: Supplemental Instruction (SI), Tutoring (both walk-in and appointment-based types), and academic coaching. For more information on AEC services, study tips, and SI session, visit the AEC website at http://web.uri.edu/aec/ .
