This exercise uses the radioactive decay model. 


A wooden artifact from an ancient tomb contains 60% of the carbon-14 that is present in living trees. How long ago was the artifact made? (The half-life of carbon-14 is 5730 years. Round your answer to the nearest whole number.)

Thank you for the opportunity to help you with your question!

0.60 = 0.5^(t/5730)

t is number of years to get to 

log(.6) = (t/5730)log(0.5)

t = 4223 years :)


Please let me know if you need any clarification. I'm always happy to answer your questions.
