DN is an option. Rank alternatives by increasing PW of total costs: DN, 1, 2 1 vs. DN: B/C = 1,020,000/840,900 = 1.21 eliminate DN 2 vs. 1: ?B = 1,850,000 – 1,020,000 = $830,000 ?C = 1,780,000 – 840,900 = $939,100 ?B/C = 830,000/939,100 = 0.88 eliminate 2 Select Alternative 1
What will be an ideal response?
Location 1 vs DN: B = $520,000
D = $90,000
C = 1,200,000(A/P,8%,10) + 80,000
= 1,200,000(0.14903) + 80,000
= $258,836
B/C = (520,000 – 90,000)/258,836
= 1.66 eliminate DN
Location 2 vs 1: ?B = 580,000 - 520,000
= $60,000
?D = 140,000 - 90,000
= $50,000
?C = [2,000,000(A/P,8%,20) + 75,000] – 258,836
= [2,000,000(0.10185) + 75,000] - 258,836
= $19,864
?B/C = (60,000 –50,000)/19,864
= 0.50 eliminate 2
