3. A large clity ls located close to a major seaport. It has been proposed that a new superhighway be built between the city and the seaport, running parallel to the present congested, two-lane highway. A group of consulting engineers has estlmated that the new highway will provide the following direct beneflts: (1) additional commerce between the city and the seaport, having a value of $50 million per year: (2) future economic growth within the region over a 10-year period, resulting in an increase of $5 million per year in commercia activity, beginning in the second year: (3) a reduction in highway accidents, resulting in a direct savings of approximately $0.8 million per year. On the other hand, the following disadvantages or dishenetits are associated with the new highway: (1 the destruction of valuable formland that currently contributes $1.3 million per year to the regional economy. i) a decrease in commercial activity along the present highway, resulting in a loss of $0.7 million per year. Assess the desitablitylBCR) of the proposed superhighway, based on a construction cost of $280 million and a yearly maintenance cost of $1.5 million. Assume a ifetime of 30 years and an interest rate of 7%, compounded annually. o. 2.42 the proposed superhighway is considered to be desirable b. 1.49. the proposed superhighway is considered to be undesirable c. 0.49, the proposed superhighway is consicered to be an exceilent alternative
