Write the equation that quantitatively expresses the capitalized cost (PW as n approaches infinity) of the following project:
A bridge is constructed for 20,000,000 at t = 0
It has an annual maintenance cost of 400,000
Every 10 years a major overhaul will be done for 1,000,000
Every 15 years a minor overhaul is done for 700,000 i = 6%.
