Hello! I need some help figuring out this problem for accounting. Please show the work or steps needed to solve the problem because I would like to look back it and use it as a guide for future problems that are similar to this one. Thank you so much! (You may need to open up the photo in a new tab or zoom in a bit since I couldn't really crop the photo properly, so I apologize for that). The red number is just so I know which question the problem corresponds to and it is not a part of the problem.
