The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
