A sample of corn from an extinct civilization has a decay rate of 9.5 decays per minute per gram of carbon. Assuming that the decay rate of C-14 in the atmosphere is 15 decays per min per gram of carbon and the 1st-order decay rate for C-14 is 1.21x10⁻⁴ years⁻¹ (i.e., the half-life = 5,730 years), what is the age of the corn. A) 2470 years B) 2940 years C) 3780 years D) 4390 years
