A hydroelectric dam would cost $50,000,000 to build, and annual maintenance cost of $1,000,000 need to be made per year. In addition to that, every 6 years, a major overhaul cost of $5,000,000 needs to be made. Assuming the interest rate of 10% per year, and the dam is expected to last indefinitely, what would be the annualized cost of the dam? (P/A, i% infinity) = A/i
