Hi, 

I believe I am missing a main component for this assignment. My professor's analysis was this: 

Analysis results;1. NOt CORRECT 36,000 Gain on sale (credit).2. NOT CORRECT 20,000 Gain on Sale (credit).3. NOT CORRECT 25,000 Goodwill (debit)

Can someone explain to me in layman's terms where I went wrong? I've attached my spreadsheet on what I did. Thank you.
