I am sorry, I really don't know. There is no one in this forum, that i know of, who would be comfortable with this question.
I strongly suggest that you post this question is mathhelpforum.com (where you are much more likely to get an answer) or perhaps in an economics forum.
If you choose to use one of these 'older' forums you should know that you will be expected to be interactive with your learning. When you post your question you should talk a little about what you already know or what exactly you don't understand.
Sorry but that is the best I can do.
