The isotope known as carbon-14 is radioactive and will decay into the stable form nitrogen-14. As long as an organism is alive, it ingests air, and the level of carbon-14 in the organism remains the same. When it dies, it no longer absorbs carbon-14 from the air, and the carbon-14 in the organism decays.
The half-life of carbon-14 is 5770 years. Assume an organic sample is 14,000 years old.
Determine how many half-lives are in 14,000 years. Then use this answer to determine what percentage of the original amount of carbon-14 remains after 14,000 years. Round your answer as a percentage to the nearest whole number.
