Question 324566: Hi, I'm trying to study a study guide that my teacher gave me but I just don't understand how he got the answer. The problem is
A fossilized leaf contains 28% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as the half-life of carbon 14.
What is the formula? Answer by Fombitz(32388) (Show Source):

To find k, use the half life information.
Work the problem in the same way.
Instead of (1/2) of the original carbon, you have 28% or 0.28 times the original amount.
Find t.
