Flood damage in the Brush Creek area averages \(\$ 7,000\) annually. Civil engineers with floodplain expertise have designed a series of small dams to restrain the flow. They will cost \(\$ 25,000\) and will involve annual maintenance charges of \(\$ 500\). What is the anticipated benefit/cost ratio if the interest rate is 6 percent, the service life is 10 years, and the salvage value is \(\$ 5,000\) ?
