The supervisor of a 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 $8000
and a useful life of 5 years. The chlorine will cost $650 per year, and the labor cost will be $800
per year. Alternatively, dry chlorine can be added manually at a cost of $1000 per year for
chlorine and $1900 per year for labor. By using the Equivalent Uniform Annual Worth or
Estimated Uniform Annual Cost methods, determine present worth analysis if the interest rate
is 10% per year. The Present Worth of chlorine gaseous is -P13,494.92 and the Present Worth of
dry chlorine is -P10,989.84.
