3. Recently unearthed discoveries in North and South American archaeological sites show that charcoal from ancient fires gave a ¹4℃ decay rate of 0.4 dpm/g. The 14C/¹2C ratio in living organisms is 1.3 x 10-¹2 with a decay rate of 15 dpm/g. What is the approximate age of the sample? The half-life of ¹4C is 5730 years.
