2. 4.49 An engineer calculated the PW values for four alternatives to develop a remotely controlled vibrations control system for offshore platform application. The results in the table use a MARR of 14% per year. Determine which alternative(s) should be selected if

(a) the alternatives are mutually exclusive, and

(b) if the projects are independent.
