Group Title
One gram of a living plant containing Carbon14, decays at about 16 disintegrations per minute. It is found that one gram of a dead plant decays at 1 disintegration per minute. The halflife of Carbon14 is about 5500 years. Calculate the probable age of the plant. Thank you.

1 dpm is about 4 half lives from the start = 16 dpm. (168421). Thus, 4 halflives X 5500 years = about 22,000 years.

1/16 rate is (1/2)^n where n = # halflives. n = 4, so 4 x 5500 = 22,000 years, as @LunarSolstice just found.
