Question
Carbon dating presumes that, as long as a plant or animal is alive, the proportion of its carbon that is 14C is
constant. The amount of 14C in an object made from harvested plants, like paper, will decline exponentially
where A represents the amount of 1"C in the object, A, represents
according to the equation 4 =Ane-0.0001213t
the amount of 14C in living organisms, and t is the time in years since the plant was harvested. If an
archeological artifact has 30% as much 14C as a living organism, how old would you predict it to be? Round to
the nearest year.
