Anthropologists can estimate the age of a bone or other sample of organic matter by its carbon-14 content. The carbon-14 in a living organism is constant until the organism dies, after which carbon-14 decayss with first order kinetics and a half life of 5730 years. Suppose a bone from an ancient human contains 19.5%of the C-14 found in living organisms. How old is the bone?
