Amammoth bone is found to contain roughly 5% of the isotope c-14. living elephant bones commonly contain about 40% c-14. given that c-14 has a half-life of 5,730 years, how long ago did this mammoth die? show your work. (hint: no complex math is needed to solve this problem)

Step-by-step explanation
The amount of C-14 has declined from 40 % to 5 % of the original, that is, to ⅛ of the original amount.
The half-life of C-14 (5730 yr) is the time it takes for half of the isotope to decay.
We can make a table of the amount remaining after each successive half-life.
