The table below contains information about an environmental clean-up project in the township of Hiles. Shorten the project three weeks by finding the minimum-cost schedule. Assume that project indirect costs and penalty costs are negligible. Identify activities to crash while minimizing the additional crash costs.

Activity	Normal Time (weeks)	Crash Time (weeks)	Cost to Crash ($ per week)	Immediate Predecessor(s)
A	5	4	250	None
B	10	9	200	None
C	8	7	270	A
D	7	4	350	A
E	3	3		B
F	1	1		C, D
G	5	3	250	D, E
H	8	7	450	F
I	1	1		G
