<PRE><B>Question 759656</B>
an artifact was found and tested for its carbon-14 content. If 87% of the original carbon-14 was still present, what is its probably age (to the nearest 100 years)? (carbon-14 has a half-life of 5730 years.)
------
Equation:
0.87Ao = Ao*(1/2)^(t/5730)
----
(1/2)^(t/5730) = 0.87
----
(t/5730) = log(0.87)/log(1/2)
-----
t/5730 = 0.2009
---
t = 1151.23 years
