Blue Property Management (Blue) owns and manages apartment buildings. Each apartment building has a dedicated room for laundry facilities. One of the laundry facilities was equipped with older laundry machines and driers that consume more electricity than the newer ones. These machines were purchased 10 years ago, and they can last for another 10 years. The management is considering replacing these old machines with new energy efficient machines. Blue's accountant has gathered the following comparison for the annual expenses: Annual Expenses Old Machines New Machines Electricity $20,400 $12,700 Water 6,000 5,200 Maintenance 4,400 6,100 Depreciation 2,800 4,000 The cost of the old machines was $56,000, and the new machines will cost $40,000. If the new machines are purchased, the old machines can be sold for $3,000 now. Both sets of machines will be disposed of in 10 years, with no residual value then. Blue's required rate of return is 6%. In general, Blue rejects projects with a payback period greater than 4 years. What is the project's payback period?
