Carbon 14 is used to determine the time an organism was living. The amount of carbon 14 an organism has is consistent with the atmosphere but when an organism dies carbon-14 decays at half-life of 5730 years. If an archaeologists measure 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
