Suppose a radioactive quantity decays according to the law Q(t) = Q02^−(t/140) where Q0 is the initial amount present and t is measured in days. (a) Find the initial amount present if it is observed that after 140 days 50 mg of the quantity is left. (b) What will be the amount of quantity left after 280 days.
