For a proposed bridge project, FDOT has estimated the capital investment, annual O&M cost, net annual benefit, and salvage value under three different scenarios (optimistic, most likely, and pessimistic). Assume the useful life of the bridge is 50 years and the interest rate is 4%, what is the estimated average B/C ratio of the proposed project?
