    For the answer to the question above,

    The amount of the substance left after sometime, t, is given by the equation,

    At = (Ai) x e^-kt

    where Ai is the initial amount and k is constant. From the given half-life,

    At / Ai = 0.5 = e^-k (12.32); k = 0.5626

    Then, for the next set,

    At/Ai = e^ (-0.5626) x24.6 = 1/4 So the answer is D.
