The Excel Homework with the Appropriate Formulas but with the Answers Omitted.

I have now completed the stuff to serve as substitute for class on Tuesday 11/7.  We won't be having class then.  In the next post I will provide the information for that.

As promised, here is the Excel file with the formulas (most of which are in column A).  I would appreciate learning from any and all of you whether you try to produce such formulas yourself before answering the questions, or if you do that all in your head without writing any of it down.  If you care to respond to that, please do so by commenting on this post, or if you prefer your privacy you can do it by email.
