Consider the project described by the table below where all durations are in days and, the normal and crash costs are in Ghana Cedis. In addition, there is a fixed cost of GHC1000 for each day on site.

Activity Predecessor Normal Time Normal Cost (GHC) Crash Time Crash Cost (GHC)

A 2 2,000 2 2,000

B 13 2,000 10 2,300

C 19 2,000 15 3,000

D A 18 2,000 15 3,000

E B 13 2,000 11 3,000

F C 10 2,000 9 3,000

G D 18 2,000 14 4,000

H E 6 2,000 5 3,000

I F 4 2,000 3 3,000

J G 13 2,000 12 3,000

K H,I 15 2,000 13 3,000

L J,K 4 2,000 4 2,000

If the project is to be completed in 53 days, the minimum total cost of the project will be GHS?
