I was wondering if there is a recording of a tutor walking through this question step by step. I am not sure how to even begin approaching the question. Thank you in advance for your help.
No there is not lecture on it and it is not in the class notes either. The amount of time and effort to be able to fully understand and repeat the calculations/double entries is not worth the effort.
If it were to come up in an exam it would be an optional question, so therefore chose the other available options.
