I need the PW of the Lead Acid and Lithium Ion.

Answer 1

R = 5%

PW of lead acid alternative = -7000 -2750*(P/A, 5%, 12) - 8000*(P/A, 5%, 6)*(P/F, 5%, 12)

PW of lead acid alternative = -7000 -2750*8.863 - 8000*5.076*.5568

PW of lead acid alternative = -$53983.8

----------

PW of the lithium ion alternative = -13000 - 2500*(P/A, 5%, 18) + 3000*(P/F, 5%, 18)

PW of the lithium ion alternative = -13000 - 2500*11.690 + 3000*.4155

PW of the lithium ion alternative = -$40978.5
