I am really struggling with an exam revision question for my MBA and would appreciate any assistance from someone skilled in ABC

What is an exam revision question?

ABC costing is a topic too big to just post about it. I can give you a link to some basic stuff about it, but if you're having trouble with something, you've got to get more specific.
Principles of Accounting Chapter 20 (http://www.principlesofaccounting.com/chapter%2020.htm#ACTIVITY-BASED%20COSTING)

It is a mini case study and it requires calculations to be done... I do understand the basic concepts of ABC, yet I for the life of me cannot figure out how to go about doing it

I have looked at the link, perhaps I can try it again, thank you
