An ancient bone shows a

^{14}\text{C}/^{12}\text{C}

ratio that is 25.0\% of the ratio in living organisms. The half-life of

^{14}\text{C}

5730\,\text{years}

. Estimate the age of the bone. a)

7.9\times 10^{3}\,\text{yr}

1.59\times 10^{4}\,\text{yr}

1.15\times 10^{4}\,\text{yr}

5.7\times 10^{3}\,\text{yr}
