A city government is considering two types of town-clump sanitary systems. Design A requires an initial outlay of $400.000 with annual operating and maintenance costs of $50.000 for the next 15 years: design B calls for an investment of $300.000 with annual operating and maintenance coSIS of $80,000 per year for the next 15 years. Fee collections from the residents would be $85.000 per year. The interest rate is 8%. and no salvage value is associated with either system.(a) By the benefit-cost ratio (BC(i)), which system should be selected?(b) If a new design (design C). which requires an initial outlay of $350,000 and annual operating and maintenance costs of $65,000, is proposed, would your answer to (a) change?
