I don't know where to find any industry averages, but will ask my instructor. Here is the excel file we were given to answer the questions I indicated above. I have until Sunday 12/4/11 at 9 PM PST to submit this. I will email you once I hear back from my instructor.
Thank you, Phoebe
Actually I think you have the industry standard in the numbers above. Here is a JPG of the problem so maybe you can see what I get (since I can't send you an excel file).
Any help you can provide would be greatly appreciated.
