In some exercises, the problems involve currency. In most of these, the student is asked to round their answer to the nearest cent. In this particular problem, the answer rounds to $538.60. Despite this, the accepted format is $538.6, and $538.60 is marked wrong. This is annoying, as it is unexpected (As it is standard when representing currency to use two decimals always), and as it ruins perfectly good streaks by the student, which can be very frustrating.
