<h3><u>Half life</u></h3>

Given that the radioactive element​ carbon-14 has a​ half-life of 5750 years, and a scientist determined that the bones from a mastodon had lost 57.5​% of their​ carbon-14, to determine how old were the bones at the time they were discovered, the following calculation must be made:

  • 50 = 5750
  • 100 = 11500
  • 57.5 = X
  • 57.5 x 11500 / 100 = X
  • 6612.5 = X

Therefore, the bones were 6612.5 years old at the time they were discovered.
