Can somebody help me with this one...Pretty plz...I need a detailed answer that shows the work..Thx
In the formula A(t)= Pekt, A(t) is the amount of radioactive material remaining from an initial amount P at a given time t and k is a negative constant determined by the nature of the material. An artifact is discovered at a certain site. If it has 78% of the carbon-14 it originally contained, what is the approximate age of artifact, rounded to the nearest year? (carbon-14 decays at the rate of 0.0125% annually).
