Q$\mathrm{.}5$Set. $($A$)$ Use the information contained below to compress one time unit per move using the least oost method. Redwee the shedule unili you reach the crash point of the network. For cach move identify what activity$($s$)$ was erathed, the affusted total cost, and explain your chotce if you hiave to choose between wctivitien that oost the same.

Note: Crash poim of the network is the point in which the duration cannoe be reduced any furtber.

$\backslash$table$[[$Activity$,$Crash Cost,Maximum,,$],[$II$,($Slope$),$Crash Time,Normal Time Normal Cost,$],[$A$,,0,4,570],[$B$,$$$60,2,5,60],[$C$,50,1,5,90],[$D$,40,2,4,70],[$E$,40,1,5,50],[$F$,50,2,5,40],[$G$,30,1,4,70],[$H$,30,1,4,80],[$I$,,0,3,40]]$

Total Direct Normal Costs $-$ $$570$

Completion Time: $21$

Total Cost $${570}_{?}$
