When balancing a nuclear equation that emits a neutron (n01), which numbers must remain equal on both sides?

Technicium-99m is a radioisotope that is widely used in medical imaging procedures.  It is supplied to  hospitals in a lead-shielded pot which contains a sample of molybdenum-99 that is generated in a nuclear facility — a nuclear power plant.  The molybdenum-99 decays to technicium-99m, and samples of technicium-99m are obtained for medical procedures in the hospital by rinsing the molybdenum sample with a saline solution that specifically solubilizes the technicium.  If the molybdenum–99 has a half life of 66 hours, and the hospital needs at least [x] percent of the molybdenum in its undecayed state for the sample to be useful, how long does the supplied sample remain useful to the hospital?  Report your answer in days, and round to an integer number of days (i.e., 5, 17, 24, etc.)
