The cost associated with maintaining rural highways follows a predictable pattern. There are usually no costs for the first 3 years, but thereafter maintenance is required for restriping, weed control, light replacement, shoulder repairs, etc. For one section of a particular highway, these costs are projected to be $6000 in year 3, $7000 in year 4, and amount increasing by $1000 per year through the highway's expected 30-year life. Assuming it is replaced with a similar roadway, what is the perpetual equivalent annual worth (in years 1 through infinity) at an interest rate of 8% per year?
