The supervisor ofa community swimming pool has developed two methods for chlorinating the pool. If gaseous chlorine is added, a chlorinator will be required that has an initial cost of RM 8,000 and a useful life of 5 years. The chlorine will cost RM 650 per year, and the labor cost will be RM 800 per year. Alternatively, dry chlorine can be added manually at a cost of RM 1,000 per year for chlorine and RM 1, 900 per year for labor.
