In 2000 an archeologist discovered a sandal made from yucca fiber that she believed was from A.D. 700. Estimate the percentage of the yucca fiber's original carbon-14 that remained when the sandal was found. Round to the nearest tenth of a percent.
---------------
Formula:
A = S (1/2)^(t/5730)
Your problem:
A = S (1/2)^(1300/5730)
A= S (0.85448...)
Amount of carbon 14 left in year 2000 is 85.45% of the original amount.
