BC Electronics has begun a project consisting of activities A$,...,$ G$.$ The following table reports, for each activity, the normal time for activity completion, the crash time for activity completion, the normal cost for activity completion, the crash cost for activity completion, and the immediate predecessors.

Activity Time $($in Weeks$)$ Cost Immediate Predessors

Normal Crash Normal Crash

A $32$ $$1100$ $$1190$ NA

B $21$ $$750$ $$850$ NA

C $11$ $$650$ $$650$ NA

D $75$ $$900$ $$1220$ A

E $63$ $$1050$ $$1560$ B

F $21$ $$1150$ $$1210$ C

G $42$ $$1500$ $$1680$ D$,$ E

The minimum project completion time has been computed with the calculations of earliest start, earliest finish, latest start and latest finish for each activity with normal activity times for each activity on the project network copied below:
