The amount of carbon 14 present after t years is given by the exponential equation A(t) = Apekt, with k = In 2 - 5600 . A sample from a refuse deposit had 52% of the carbon 14 found in a contemporary living sample. How old was the sample? The sample was about years old. (Round to the nearest hundred as needed.)
