Aradioactive isotope takes 80 minutes to decay from 64 grams to 4 grams. let y(t) denote the amount of the isotope (in grams) present after t minutes.
1. find the constant c and k such that y(t)=ce^-kt

2. how long do we have to wait (in minutes) if we want the mass of the isotope to drop below 1 gram?
