Finance Subj Matter, accounting homework help

I have just started my Finance class and I am totally lost. I didn’t do well in Accounting and this is similar subject matter. I have uploaded several screenshots of questions broken down as Chapters (Chapter’s 5, 6, 7 & 8). Two chapters have a couple of questions that have Excel sheets that need to be used. I gave instructions on the Word Docs. Please help! If this goes well, I’ll use you for the next four weeks!
