I'm getting really frustrated on how to do the math by hand and not by excel and had the assignment turned back to me twice..

Someone please help and explain this... DO NOT POST FROM EXCEL. This is the third time I've asked for help and I do not understand excel!

There is a pre-filled chart but I cannot get the number correct that are pre-filled
