Solution: 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 yr
B. 7.6 x 102 yr
C. 1.1 x 103 yr
D. 9.5 x 103 yr
