The book I'm using is Managerial Accounting: Creating value in a

dynamic business environment 9th edition by Ronald Hilton. The

book's ISBN is 978-0-07-811091-7

Need help with Case 11-55 on pages 501-502. I have the solution

for problems 1-3 (even though I'm not 100% sure if they are

correct), but I'm strugling with problems 4 and 5. If someone could

come up with step-by-steps to get the answers for every question I

would really appreciate it.

Note: If it matters, the class I'm taking is Managerial

Accounting MBAA 517 not BA 312.
