Eliminating pollution If the pollution of Lake Erie were stopped suddenly, it has been estimated that the level y of pollutants would decrease according to the formula y = yoe-0.3821, where t is the time in years and y, is the pol- lutant level at which further pollution ceased. How many years would it take to clear 50% of the pollutants?
