Answer: The initial project duration is 63 weeks thanks to the valuable contributions of path
ACDFHI. Path ABEGHI is 47 weeks and path ABDFHI is 59 weeks long. The base project cost
is $11,700.
Purchases from least expensive to most expensive are as follows:
Activity D reduced 4 days for $300
Activity A reduced 2 days for $500
Activity C reduced 2 days for $600
Activity I reduced 2 days for $600
Activity H reduced 3 days for $1,000
Activity F reduced 1 day for $450
The new project length is 49 days with path lengths of ACDFHI-49; ABEGHI=40; and
ABDFHI=45. The total project cost is now $15,150.
