Roberta Bloom - Mathematics

Math 11 Chapter 6 Finance

Two Worksheets will be assigned for this chapter. 
Information about the worksheets will be given in class.  The worksheets have individual data for each student so are not posted here.  The web handout below for Adjustable Rate Mortgages is helpful for one of the worksheets.

Understanding Adjustable Rate Mortgage - how it works



Section 6.1: 1-9 odd (and 2-10 even are good extra practice if you need it.)

Section 6.2: 1-15 odd (and 2-14 even are good extra practice if you need it.)

Section 6.3: 1,3,5,7,11 (and 2, 4, 6, 8, 12 are good extra practice if you need it.)

Section 6.4: 1,3,5,7,9,11 (and 2, 4, 6, 8, 10 are good extra practice if you need it.)

Section 6.5: 1,2,3,4,5,7,9,10,11,12,13,15, 17 (and 8, 14, 16, 18 are good extra practice if you need it).  In this section I listed even numbered problems as assigned when there are two consective problems that relate to each other {1,2,3,4} of {9,10} of {11,12}.

Section 6.6: We are not explicitly doing this section in class.  I am already talking about the topic of this section as I discuss how to identify what is going on in each problem as we work on them in class.  You should do problems in this section as practice to help you master identifying the type of problem when problems are mixed together in context.

Section 6.7: Review Section: All problems are good practice for this chapter

Its recommended that you do as many suggested "extra problems" as you need to master this material - so that you can recognize quickly what problems are asking and be proficient enough to put together and solve problems in a short amount of time. Some students may need more or less practice than others to master the material.

In section 6.2 do not do problem 16 - we did not cover the "rule of 70" .  The rule of 70 is a method of approximating the time needed to double an investment.  In our class we are expected to use logs to solve exactly for t if we are asked to find the length of time for an investment.  Using the rule of 70 is not acceptable in this class.

In section 6.3 skip problems 9 and 10 - they cover payments at the beginning of the period instead of at the end of the period.  We did not cover that in class. If you wish to do those problems, you can read in the textbook about how to adjust the calculations when payments are at the beginning of the period.

In section 6.4, question 12 is sometimes ambiguous, in my  opinion, and may be difficult to understand exactly what it is asking, so I don't assign it.  If you want to try it and understand what it is asking , its OK to do.

In section 6.5, #6 is not assigned as we will do an amortization schedule as a worksheet instead.

In section 6.5 #14 and #16 are highly recommended as extra practice in finding the fair market value (selling price) of a bond.
