Consider the following EOY cash flows for two mutually exclusive alternatives $($one must be chosen$).$ The MARR is $10\%$

per year.

Click the icon to view the interest and annuity table for discrete compounding when $i=10\%$ per year.

$($a$)$ Determine which alternative should be selected based on the PW method. Assume repeatability and use a study

period of $18$ years.

The PW of the Lead Acid is $$,.($Round to the nearest dollar.$)$

The PW of the Lithium lon is $$.($Round to the nearest dollar.$)$

Which alternative should be selected? Choose the correct answer below.

Lithium Ion

Lead Acid

$($b$)$ Determine which alternative should be selected based on the AW method, also assuming repeatability.

The AW of the Lead Acid is $ $.($Round to the nearest dollar.$)$

The AW of the Lithium lon is $$,.($Round to the nearest dollar.$)$
