Please solve without using excel, solve using formulas or tables A commercial 3D printer is purchased for $340,000. The salvage value of the printer decreases by 50% each year that it is held. The cost to operate and maintain the machine the first year it is used is $13,000; these costs increase by $6,000 each year. What is the optimal replacement interval and minimum EUAC for the printer, assuming a MARR of 15% is used?Click [here](#) to access the TVM Factor Table Calculator.ORI: [input box] yearsEUAC*: $ [input box]Carry all interim calculations to 5 decimal places and then round your final answers to a whole number. The tolerance is ±5 for the EUAC*.

The term "optimal replacement period" describes how long it makes sense to replace an asset with a new one. It changes based on a number of variables, including the asset's cost, maintenance expenses, salvage value, and interest rate.The purchase price is equal to $340,000. The salvage value falls by 50% each year. Fall in salvage value equals the depreciation.Operating cost in the first year is $13,000 which rises by $6,000 each year. Also, for each year the machine (printer) is retained, the owner is sacrificing the interest that could be received on the market value each year.Table:- optimal replacement periodYearValue of machine ($)Amount of depreciation ($)(A)Operating Cost ($)(B)Foregone Interest ($)(C)Marginal cost ($)(A+B+C)03400005100051000117000017000013,000255002085002850008500019,000127501167503425004250025,0006375738754212502125031,0003187.555437.55106251062537,0001593.7549218.7565312.55312.543,000796.87549109.37572656.252656.2549,000398.437552054.6875It can be observed that the marginal cost of the machine keeps falling till 6th year, and after that, it starts rising. So, the optimal replacement period is 6 years.The MARR is 15%. The number of years is 6.The minimum EUAC will be calculated as:EUAC is $115,425.Final Answer:- ORI is 6 years.EUAC is $115,425.
