A machine that was used for 8 years has a market value of $2500 now, which decreases by $100 each year for the next 5 years. Maintenance costs this year are $5k, and for the next 5 years they are estimated at $6k, $7k, $8k and $9k. Determine the marginal cost of extending the service for two years if the MARR is 12%. Fill the whites with the results. a) Fill the whites: The loss of value in the market in year 2 is $ The loss in interest in the year 2 $ . The Marginal Cost in year 2 is $ b) If the minimum EUAC of the machine is $5500, when should the machine be replaced? Anus . (0,1,2,3,4 or 5)
