Two chemical processes have been developed by Hewey, Looie and Dewey, our process chemists. Process 1 is called PM - Pure Magic, and has an initial cost of 750K. operating cost of 60Kpy, and salvage of 80K after 2 yr. life. Process 2 - called BS, has initial cost of 1.35 million. Operating cost of 25kpy, and 120K salvage after 4 years life. BS also needs to be updated after year 2 at a cost of 90K. Using FWA select the right process if MARR is 12%pa.
