Three different technologies are being considered for a project to provide a given service. Assume that the quantity and quality of the service are identical for the three options. Project A has a life of 7 years, project B has a life of 5 years and project C has a life of 9 years. The investment and operating costs for the three projects are as shown in the table below:

Project 0 1 2 3 4 5 6 7 8 9 A −1200 −250 −250 −250 −250 −250 −250 −250 B − 800 −400 −400 −400 −400 −400 C −1500 −200 −200 −200 −200 −200 −200 −200 −200 −200 Rank the three options using the Annual Equivalent Cost method.
