# Math Help - Interest compounded

thanks

2. ## Re: Interest compounded

There is a slight ambiguity in your question. In the case of quarterly compounding, it's not clear whether the $300 was withdrawn before or after the compounding date. If "so many months ago" is calculated from today (Pearl Harbor Day, 12/7) then the compounding would be calculated before the$300 withdrawal and you'd have a few dollars more.
