An engineer calculated the PW values for four alternatives to develop a remotely controlled vibrations control system for offshore platform applications. The results in the table use a MARR of 14% per year.

Alternative	I	J	K	L
Life,n, years	3	4	12	6
PW overnyears, $	16.08	31.12	257.46	-100
PW over 6 years, $	26.94	15.78	653.29	-100
PW over 12 years, $	39.21	60.45	257.46	-100

Determine which alternative(s) should be selected if the projects are independent.
