An oil company has installed an offshore production facility for $10 million. The annual maintenance cost of the facility is $60,000 per year for the first year, increasing by $10,000 per year for the next 9 years. In the 11th year, a major overhaul is conducted at a cost of $500,000. The overhaul has helped in keeping the maintenance cost fixed at $150,000 per year for the remaining 10 years. At the end of 20 years, the facility is sold for a sum of $2 million. If the market interest rate is 8%, calculate the present value of all the cost over the 20 years period. Also, calculate the equivalent annual cost of the facility.
