Consider the following EOY cash flows for two mutually exclusive alternatives (one must be chosen) The MARR is 4% per year Lead Acid $9,000 $2,750 Lithium Ion Capital investment Annual expenses Useful life Market value at end of useful life $15,000 $2,200 12 years18 years $3,000 $0 Click the icon to view the interest and annuity table for discrete compounding when 54% (a) Determine which alternative should be selected based on the PW method. Assume repeatability and use a study period of 36 years The PW of the Lead Acid is S 70100 (Round to the nearest hundreds.) The PW of the Lithium lon is $63200 (Round to the nearest hundreds) Which alternative should be selected? Choose the correct answer below Y Lithium lon Lead Acid (b) would the selected alternative remain the same if the MARR were 8967 The PW of the Lead Acid is $ -46200 (Round to the nearest hundreds) The PW of the Lithium, lon is SF42700 (Round to the nearest hundreds.) Which alternative should be selected? Choose the correct answer below ALithium lon Lead Acid
