A 10.00-g plant fossil from an archaeological site is found to have a 14C activity of 3094 disintegrations over a period of ten hours. A living plant is found to have a 14C activity of 9207 disintegrations over the same period of time for an equivalent amount of sample with respect to the total con- tents of carbon. Given that the half-life of 14C is 5715 years, how old is the plant fossil?

Question
Can you please show me how to solve this question. Thank you very much
A 100.0-g plant fossil from an archaeological site is found to have a \(^{14}C\) activity of 3094 disintegrations over a period of ten hours. A living plant is found to have a \(^{14}C\) activity of 9207 disintegrations over the same period of time for an equivalent amount of sample with respect to the total contents of carbon. Given that the half-life of \(^{14}C\) is 5715 years, how old is the plant fossil?
