Answer:
The mammoth died 17.190 years ago.
Step-by-step explanation:
Given information:
- Half-life of C-14 is 5.700 years.
- Living elephant bones commonly contain about 40% C-14.
For every 5700 years, the elephant's bones losses a half-life of C-14. And supposing that the living mammoth bones had the same percentage of C-14.
If the mammoth when living has 40%, then:
- After 5.730 years, the mammoth bones will contain 20%.
- After 11.460 years(2 half-lives), the mammoth bones will contain 10%.
- After 17.190 years(3 half-lives), the mammoth bones will contain 5%.
