I'm having a really, really hard time understanding this question, perhaps because of the mathematical formula/structure used. Was there a lesson tied to this type of math used in the LSAT? I know there were some in the CC that used proportions or anything, but anything more similar to this?

I picked E, and the explanation of why it's not relevant/why it's wrong isn't really sinking. I kind of figured all of the answer choices are bad, because I'm thinking about it as: Raisins have more iron than grapes, despite the fact nothing is added and nothing is removed from grapes.

Okay, so why are there more calories then? Well, maybe it's because people eat them with other things?? Like for it to be a calorie it needs to be digested/eaten??? Is that too much of an assumption??? SIGH IM SO LOST :( #Help
