Kingsville plans to buy a street-cleaning machine. A used cleaning vehicle will cost $80,000 and have a $10,000 salvage value at the end of its five year life. A new system with advanced features will cost $160,000 and have a $45,000 salvage value at the end of its five year life. The new system is expected to reduce labor hours compared with the used system. Current street cleaning activity requires the used system to operate 8 hours per day for 20 days per month. Labor costs $50 per hour and MARR is 12% per year. Find the breakeven labor hours for the new system.
