An archeologist runs a carbon dating test on bones found in Olduvai Gorge in Tanzania. She discovers that the carbon-14 isotopes in the bones have undergone three half-lives. Carbon-14 has a half-life of 5,730 years. Approximately how old are the bones? 1,910 years old

3,000 years old

5,730 years old

17,190 years old
