After this period, the system database can still be used in the replacement system, saving approximately $12,000. The current system has annual operating costs of $120,000, whereas the annual operating costs for the new system after installation is estimated at only $90,000. The new system has additional benefits estimated at $12,000 per year. All estimates for costs and benefits are assumed to increase at a rate of 10% annually for both the current system and the new system. Do a cost-benefit analysis using the following methods: 1.
