We can use a formula for carbon 14 dating to find the answer. Where t 1/2 is the half-life of the isotope carbon 14, t is the age of the fossil (or the date of death) and ln() is the natural logarithm function. If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.
