A telephone company is considering building a new automated switching distribution substation with a useful life of 20 years to support new suburban developments.
The substation is located in a state in which the combined tax rate is 40%, and the telephone company uses a 15% real interest MARR to assess capital investment projects.
Estimated real dollar revenues and costs are as follows:
