i received a private message regarding this problem.
brian has already addressed the problem in sufficient detail -- but, in case anyone is still confused, you should check out the problem on which this one is modeled. it's an OG 10th / OG Verbal supplement problem starting with the words "A certain mayor has proposed a fee of five dollars per day..." (i can't quote the whole problem here, for copyright-related reasons).
this problem and that problem are extremely similar in both structure and reasoning, so you could probably use that one to help you understand this one. in fact, the answer choices are even in the same order -- this (a) has the same reasoning as that (a), this (b) as the same reasoning as that (b), and so on.
