An injection molding system has a first cost of $190,000 and an annual operating cost of $71,000 in years 1 and 2, increasing by $6,000 per year thereafter. The salvage value of the system is 25% of the first cost regardless of when the system is retired within its maximum useful life of 5 years. Using a MARR of 10% per year, determine the ESL and the respective AW value of the system.
The ESL is 5 year(s) and AW value of the system is $ .
