Answer:
The age of the organism is approximately 11460 years.
Explanation:
The amount of carbon-14 decays exponentially in time and is defined by the following equation:
 (1)
 (1)
Where:
 - Initial amount of carbon-14.
 - Initial amount of carbon-14.
 - Current amount of carbon-14.
 - Current amount of carbon-14.
 - Time, measured in years.
 - Time, measured in years. 
 - Time constant, measured in years.
 - Time constant, measured in years. 
Then, we clear the time within the formula:
 (2)
 (2)
In addition, time constant can be calculated by means of half-life of carbon-14 ( ), measured in years:
), measured in years:

If we know that  and
 and  , then the age of the organism is:
, then the age of the organism is:




The age of the organism is approximately 11460 years.
