Lesson 3a.
This Lesson asks you to redo the Problems from Lesson 3.

This time, read the instructions carefully. I have added a few comments below.

NOTE 1: Be sure to read  Homework Format  and Homework Writing Policy  BEFORE writing up your solutions to be turned in.

NOTE 2: When two or more Lessons are to be turned in on the same day, please staple the Lessons separately and turn them in separately.

2.5 Problems:

If you have previously done Lesson 3 correctly, you can turn that in for Lesson 3a. (But label it Lesson 3a.)
Read the instructions below carefully, and follow them. In particular, note that you are supposed to solve without a calculator or computer.
Note that you are asked to solve TWO DIFFERENT (but very similar) problems; first, Problem 1.7 from the textbook; second, the same problem with different data.

Solve Problem 2.7 without a calculator (or computer, etc.), using only the numerical fact that  (1.1)²⁰ = 6.727450... . (Use the methods of Chapter 2. You don't need, although you could use, an annuity formula from Chapter 4.)

Also, solve the same problem with the data changed as follows:

The relevant ages are 30, 45, and 60, instead of 25, 45, and 65, as given in Problem 2.7.
The interest rate is 7% instead of 10%.
(You should be able to do this problem using only one calculator calculation, analogous to the value of  (1.1)²⁰  given above.)

NOTE: Be sure to read  Homework Format  and Homework Writing Policy  BEFORE writing up your solutions to be turned in.

NOTE: As stated on the Course Home Page, all due dates are tentative. Assignments, or parts of assignments, may be postponed to a later date.
