I am doing an introduction to accounting class (we are doing Cost Accounting) , and one of the questions I have for an assignment asks you: "Costs are a matter of opinion. Discuss why this might be so". The lecturer is hopeless and I think this question is too vague to answer. My answer so far: It's a bit messy. The answer is to be 400 words, this is only 200 and I feel like I'm beating about the bush with the answer. Any help would be appreciated.
