The activity of carbon 14 in living tissue is 15.3 disintegrations per minute per gram of carbon. The limit for reliable determination of age is based on carbon 14 is .10 disintegration per min per gram of carbon. Calculate the max age of a sample that can be dated accurately by radiocarbon dating. The half life is 5730 years.

If the half life is 5730 I get 0.123 years for k. The constant. How do I use the other information to get the max age of the sample?
