A conveyor system costs $100,000 to install. The salvage value of the conveyor system decreases by $20,000 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 $20,000; this cost increases by 5% per year. What is the optimal replacement interval and minimum EUAC for the conveyor system, assuming a MARR of 12% is used?
