I'm not entirely sure, but I think it would have gone through a halflife and would therefore be about 5370 years old. I'm not sure on the halflife either, but you can definitely look that up.

Missing data: actual half-life of C-14. I do not memorize stuff like these, See text.
Anyway, for the sake of argument that half-life is 5000 years.
From the data of counts, it has decreased by HALF, so one half life has passed, so the artifact is 5000 years old. If the counts is 4, then the artifact is 10,000 years old.

i dont recommend dating radiostopics as they are rarely faithful and often let all their friends see those nude pics you let them take during intimate moments
