You are considering switching your irrigation system from a Mid Elevation Spray Application (MESA) system to a Low Elevation Spray Application (LESA) system. The benefit of the switch is that you will use less energy, less water and potentially realize higher crop yields. The LESA dealer estimates that to convert your current irrigation system, it will cost you $42,000 today. You expect the system to last for 15 years. After visiting with your crop consultant, you determine that the LESA system will save you $7,600 per year. It will cost $2,800 to maintain every year. At the end of fifteen years, your contract with the company states that they will buy the system back for $2,000. You assume a 6.5% annual intrest rate on all new investment. Should you purchase the system?
