"but have no idea where to start"
He clearly isn't asking for the answer directly. He want's an understanding of the question, not the direct answer. Like me, he probably needed help on this question late at night (past 12am) and so couldn't ask anybody on fb or irl.
The responce provided by "Melody" helped immedietely, and I was able to answer the question within about 20 minutes. Melody didn't provide any actual answers to any questions. He gave an example and expects you to calculate the rest based on that.
Thank you Melody, as it was later at night and I had nobody to ask (also the same university).
Edit: Interesting that you found this topic in the first place whoever "heydudestopit" is. Any particular reason to be googling the question if you didn't intend to get more information from sources other than the university? It's a bit sus you found this topic in the first place.
