In the formula A=I e^(kt),

A is the amount of material remaining from an initial amount I at a given time t and k is negative constant determined by the nature of the material.

If it has 53% of the carbon it originally contained, what is the approximate age of the artifact? (carbon decays @ a rate of 0.0125% annually.) Round to the nearest year.

What formula do I use??

4240 yr

5079 yr
