Situation:
Find the age of the mammal hide to the nearest
year
A farmer in China discovers a mammal
hide that contains 71% of its original
amount of C-14.
Enter the correct answer

No - inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k = 0.0001
t = time, in years

formula: final amount=initial amount*(1/2)^(time/half-life), or t=ln(final amount/initial amount)/(-0.693)*half-life. The half life of C-14 is 5730 years, and final amount=initial amount is 71% or 0.71, so t=ln(0.71)/(-0.693)*5730=2832 years approximately.
