(a)
A polluted pool has an initial concentration of bacteria of 10* part/m³, while the
acceptable level is only 5 x 103 part/m³. The concentration of the bacteria will
reduce as fresh water enter the pool. The differential equation that governs the
concentration C of the pollutant as a function of time (in weeks) is given by:
