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.

$\backslash$table$[[$Activity$,\backslash$table$[[$Normal Time$],[($weeks$)]],\backslash$table$[[$Crash Time$],[($weeks$)]],\backslash$table$[[$Cost to Crash$],[($$ per week$)]],$Immediate Predecessor$($s$)],[$A$,5,4,300,$None$],[$B$,7,4,50,$None$],[$C$,7,6,300,$A$],[$D$,7,6,250,$A$],[$E$,1,1,-,$B$],[$F$,3,3,-,$C$,$ D$],[$G$,5,4,200,$D$,$ E$],[$H$,4,2,200,$F$],[$I$,2,2,-,$G$]]$

Fill in the table below with the activity times after crashing to show the resulting schedule. $($Enter your responses as whole numbers.$)$
