Derive the equation to compute the equivalent annual cost given the capital cost of a highway, such that A = (A/P) P, where A/P is the capital recovery factor. (Use the following as necessary: P for the present worth, i for the annual interest as a decimal number, and n for the number of years.) A = Compute the equivalent annual cost (in dollars) if the capital cost of a transportation project is $400,000, annual interest = 8.4%, and n = 25 years. (Enter your answer as a positive value.) $
