In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of
the first day of the experiment the mass of the
substance was 1000 grams and mass was
decreasing by 14% per day. Determine the
mass of the radioactive sample at the
beginning of the 10th day of the experiment.
Round to the nearest tenth (if necessary).
