A proposed bridge on the interstate highway system is being considered at the cost of $2 million. It is expected that the bridge will last 20 years. Construction costs will be paid by the federal and state governments. Operation and maintenance costs are estimated to be $180,000 per year. Benefits to the public estimated to be $650,000 per year. The building of the bridge will result in an estimated dis-benefit of $250,000 per year to the general public. The project requires a 10% return. Determine the B/C ratio of the project.
