The alternatives listed below are compared using the annual worth criterion. With an annual interest rate of 10%, the values of n that would be used in the factors (A/P,i,n) so that comparison is correct for the Annual Value method are: 

	A	B
Initial Cost	-50,000	-90,000
Annual Cost	-10,000	-4,000
Salvage value	13,000	15,000
Life, years	3	6

a. n =3 years for A y 3 years for B b. n =3 yeers for A y 6 years for B c. Either a or b previous options d. Neither a. or b.
