An injection molding system has a first cost of $$180,000$ and an

annual operating cost of $$77,000$ 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.$$The ESL is$$ year$($s$)$ and AW value of the

system is $$$
