Carbon-14 is used to determine the time an organism was living. The amount of carbon-14 an organism has is constant with
the atmosphere, but when an organism dies the carbon-14 decays at a half-life of 5,730 years. If an archeologist measured the
amount of carbon-14 in an organism and it was 25% of the total amount of atmospheric C-14, what is the age of the organism?
1432.5 years
