Answer:
Projects C, D and B should be carried out since they yield the highest profits. Total investment = $12.5 million.
I based my decision on how much value each project generated (NPV) and how profitable they were. If the company really needed to invest as much of the $14 million as possible, then you could change project D for E, fro a total investment of $13.5 million. Projects B and F yield basically the same gains, but the investment for project F is too high and there are better alternatives.
Step-by-step explanation:
Project Initial Investment Length in Years Annual Cash Flow
A $3.0 million 6 $719,374
B $3.5 million 5 $970,934
C $4.0 million 7 $904,443
D $5.0 million 4 $1,716,024
E $6.0 million 6 $1,500,919
F $7.0 million 5 $1,941,868
G $8.0 million 7 $1,725,240
NPV
A = -$3.0 million + (4.29218 x $719,374) = -$3.0 million + $3,087,682.70 = $87,682.70
B = -$3.5 million + (3.74286 x $970,934) = -$3.5 million + $3,634,070.03 = $134,070.03
C = -$4.0 million + (4.7893 x $904,443) = -$4.0 million + $4,331,648.86 = $331,648.86
D = -$5.0 million + (3.13586 x $1,716,024) = -$5.0 million + $5,381,211.02 = $381,211.02
E = -$6.0 million + (4.29218 x $1,500,919) = -$6.0 million + $6,442,214.51 = $442,214.51
F = -$7.0 million + (3.74286 x $1,941,868) = -$7.0 million + $7,268,140.06 = $268,140.06
G = -$8.0 million + (4.7893 x $1,725,240) = -$8.0 million + $8,262,691.93 = $262,691.93
Profitability index
A = NPV / initial investment = $87,682.70 / $3,000,000 = 2.92%
B = NPV / initial investment = $134,070.03 / $3,500,000 = 3.83%
C = NPV / initial investment = $331,648.86 / $4,000,000 = 8.28%
D = NPV / initial investment = $381,211.02 / $5,000,000 = 7.62%
E = NPV / initial investment = $442,214.51 / $6,000,000 = 7.37%
F = NPV / initial investment = $268,140.06 / $7,000,000 = 3.83%
G = NPV / initial investment = $262,691.93 / $8,000,000 = 3.28%
ranking of projects based on profitability
C = $4 million investment, 8.28%
D = $5 million investment, 7.62% mutually exclusive with E
E = $6 million investment, 7.37% mutually exclusive with D
B = $3.5 million investment, 3.83% mutually exclusive with A
F = $7 million investment, 3.83%
G = $8 million investment, 3.28%
A = $3 million investment, 2.92% mutually exclusive with B
Projects C, D and B should be carried out since they yield the highest profits. Total investment = $12.5 million.
