Ahiker in africa discovers a skull that contains 32% of its original amount of c-14. find the age of the skull.

according to  a formula that i found online, we have

t = [ ln (n / n0) / (-0.693) ]  * 5730          where t is the age of the fossil, n / n0  is the percent of  c-14 that remains and 5730 is the half-life of c- we have

t = ( ln (.63) / (-0.693)) * 5730 = about 3820 yrs old
