# Problem: Carbon-14, which is present in all living tissue radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of  13.6 counts per minute. If the half-life for carbon-14 is 5720 years, how old is a wood sample that gives a rate for carbon-14 decay of 11.9 counts per minute?A. 5.3 x 102 yrB. 7.6 x 102 yrC. 1.1 x 103 yrD. 9.5 x 103 yr
