Why isn't the answer just infinity?

The question at the end of the video is "For how many values of n is rounding down of n/5 equal to 28?" If n is any real number in the interval [140,145) then this particular n would satisfy this question. Thus, the answer should just be infinity, for there are an infinite number of ways to satisfy n being in the range of that interval.
