The Radioactive Element Carbon

The radioactive element carbon- 14 has a haif-life of 5750 years. A scientist determined that the bones from a mastodon had lost
83.9%
of their carbon-14. How old were the bones at the time they were discovered? The bones were about years old. (Round to the nearest integer as needed.)
