Hello, I am working on a homework question on MyFinanceLab for FIN 302 (Managerial Finance). I am stuck on the last piece of the problem. I have attached all of my work for this problem so far. Unfortunately my problem was reset and now I have new numbers to work with, but I mostly just need to understand how to work out part C of the problem. The "helper" on MyFinanceLab gave me the answer finally, without explaining how to get to the answer, so I know the answer is $655592. Any help you can offer on this would be greatly appreciated.

Thanks!
