The age of an ancient artifact can be determined by the amount of radioactive carbon-14 remaining in it. If D0 is the original amount of carbon-14 and D is the amount remaining, then the artifact's age A (in years) is given by
A = −8267 ln
D
D0
.
Find the age of an object if the amount D of carbon-14 that remains in the object is 84% of the original amount D0. (Round your answer to the nearest whole number.)

A =  yr
