A local church, High$-$as$-$a$-$Kite, decides to purchase a vehicle for $$220,000.$ The vehicle will have a salvage value of $$20,000$ after a uscful life of five years. The new vehicle will replace an old vehicle. The old vehicle can be sold for a salvage value of $$10,000.$ The church will rent the vehicle out when it isn't being used at church and as a result it will create contribution margin of $$65,625$ per year. The only fixed expense the vehicle will have is the annual depreciation of $$40,000$ per year. What is the payback period for this investment?
