Question:

Archaeology: carbon-14 dating. The radioactive carbon-14 (14C) in an organism at the time of its death decays according to the equation
A = A0e-0.000124t
where t is time in years and A0 is the amount of 14C present at time i = 0.Estimate the age of a skull uncovered in an archaeological site if 10% of original amount of 14C is still present.[find t such that A = 0.1A0.]
