My first question is why you don't understand any of it. Have you been keeping up to date with the work and geting help from your instructor as required?
My second question is why have you left this until the very last moment.
My final remark is that if you want help it's expected that you show some sort of effort. I personally find it galling that you would include the instruction "Please place all your work in one Excel file and place it in the Assignments folder". This to me shows absolutely no thought on your part in what you're posting here.
