Question: hii currently have an assignment and i am very confused...

Hi,

I currently have an assignment and I am very confused, especially on the question about the spending on net working capital and how during the final year they are reversed. Im also a bit lost on how to correctly do each step. This is what I have done so far in excel. The project is operated over a 10 year period. 
 

 

Thank you in advance for your help!
