A conveyor system costs $90.000 to install. The salvage value of the conveyor system decreases by $18,000 each year until its salvage value is $0, at which point it no longer decreases. The cost to operate and maintain the conveyor system the first year is $18,000; this cost increases by 6% per year. What is the optimal replacement interval and minimum EUAC for the conveyor system, assuming a MARR of 10% is used? Click here to access the TVM Factor Table Calculator. ORI: years EUAC': $ Carry all interim calculations to 5 decimal places and then round your final answers to a whole number. The tolerance is 10 for the EUAC
