The age of an ancient artifact can be determined by the amount of radioactive carbon-14 remaining in it. If  figure 2.png)
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 = 8267ln  figure 1.png)
. Find the age of an object if the amount D of carbon-14 that remains in the object is 85% of the original amount  figure 2.png)
.
