The age of an ancient artifact can be determined by the amount of radioactive carbon 14 remaining in it. If D0 is the orginal amount of carbon 14 and D is the amount remaining, then the artifacts age A (in years) is given by
A= -8267ln (D/D0)
Find the age of an object if the amount D of carbon-14 that remains in the object is 74% of the original amount D 0.
(Hint: If 74% remains, then the ratio D/Do=.74)
Which is the answer??
A. approx. 2700 years
B. approx. 2900 years
C. approx. 2200 years
D. approx. 2500 years
E. approx. 2400 years
