Big-J Construction Company, Inc. (Big-J CC) is conducting routine periodic review of existing field equipment. The owner of Big-J CC has asked for a replacement evaluation of a paving machine now in use. A newer, more efficient machine is being considered. The old machine was purchased 3 years ago for \$200,000, and yearly operating and maintenance costs are as follows. Big-J CC Uses a MARR of 20%; the current market value of the paver is \$120,000.
