Jane is using a 10% annual interest rate to decide between three options: Model A, B or C.

	Model (A)	Model (B)	Model (C)
Initial Cost	$5,000	$2,000	$7,500
Life (years)	4	4	4
Annual Savings	$1,500	$650	$2,500

22. Would the above decision change if the product life for all three models are 5 years instead of 4 years? Would the above decision change if PW analysis is applied instead of AW analysis?
    1. Yes, for both changes
    2. Yes on 5 years, but no on PW
    3. No on 5 years, but yes on PW analysis
    4. No for both change
    5. Cant answer this question as we need more information to compute AW and PW of the new scenarios
