# If a sample of organic material contains 1/8 of the radioactive "^14C than a modern day sample and the half-life for "^14C is 5,730 years, approximately how old is the order sample of organic material?

$\frac{1}{8} = \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2}$ or three half lives.
$3 \times 5730 = 17190$
