One other (obvious) point is that the SAT is a multiple choice test. So yes, it's possible that they want some complicated analysis where it would matter whether the interest was paid on the first of the month or the last, but I bet it wouldn't. Specifically, if you think "hmm, do they mean A or B or C" then you could do the math for A, B, and C, and see which if any of those answers appear as a possibility. In all likelihood, only one of them would.
