A company is planning to manufacture a new battery using an existing machine. Producing every 1,000 units takes 14 hours. The historical data for machine hours and total maintenance costs over the last four years are as follows: - Year 1: 5,000 hours, $850,000 - Year 2: 4,400 hours, $735,000 - Year 3: 4,850 hours, $815,000 - Year 4: 1,800 hours, $450,000 If the maximum capacity of the machine is 5,000 hours, what is the estimated maintenance cost (using the high-low method) if production is at 80% of maximum capacity?
