The city of Mersey is planning to construct a bridge across the Cavendashim river. The first cost of the bridge will be $6,453,499. Annual maintenance and repairs will be $27,310 for the first 5 years, and then will increase to $44,610 for each of the next 10 years. For the final 5 years, the annual maintenance and repairs will increase again to $54,200 per year. A major overhaul of $422,910 will be performed at the end of year 8. Using an interest rate of 5%, what is the equivalent uniform annual cost for the 20-year period? Hint: Since this is an equivalent uniform annual cost, do you need to indicate that as negative? See example 6-3 and 6-4 in the book
