Hello there,I just wanted to tell you that I managed to finish your requested work. I try to finish it as early as possible because I know it took some time for me to get online and offer my help. As always I am attaching to this message an excel file which contains tabs with all the requested problems. Where it was the case I included all the calculus, but most of the exercises were designed in such way they could be solved by using Excel functions. So in those situations, I included the function I used in the cell so the professor can see that you understood the mechanism to solve it.Looking forward to hearing from you.
