14. Lane is on her rst dig at an archeological site. She is very excited because some pottery cups and bowls were found in what looks like an ancient re pit along with some partially burned wood. Her professor gures the pottery is roughly the same age as the wood. Lana is asked to put the wood through a carbon dating test. She found that only 15% of the original carbon-14 still remains in the wood. Since her professor assumed that the wood was roughly the same age as the pottery, how old are the dishes if the half-life of carbon-14 is 5570 years
