A proposed steel bridge has a life of 50 years. The initial cost is $350,000, and the annual maintenance cost is $12,000. The bridge deck will be resurfaced every 10 years (in years 10, 20, 30, and 40) for $90,000, and anticorrosion paint will be applied every 5 years (in years 5, 10, 15, . . . , 45) for $22,000. If the interest rate is 5%, what is the EAC?
