c$.$ Demonstrate the crashing steps needed to minimize the cost of crashing down to various project lengths. Consider project lengths of $18,17,16,15,14,$ and $13$ weeks. For each possible step down in project length, specify which activity would be crashed to achieve that length, compute the resultant length of each path in the project, and compute the crashing costs as shown in the table below.

Note: Leave no cells blank $-$ be certain to enter $"O"$ wherever required.

$\backslash$table$[[$Project Duration:,$\backslash$table$[[18],[$Weeks$]],\backslash$table$[[17],[$Weeks$]],16$ Weeks,$15$ Weeks,$14$ Weeks,$13$ Weeks$],[\backslash$table$[[$Length of path$],[$ABEG$]],,,,,,],[$Length of path ACG,,,,,,$],[\backslash$table$[[$Length of path$],[$ADFG$]],,,,,,],[$Activity crashed,,,,,,$],[$Crash cost for this step,,,,,,$],[$Cumulative crash cost,,,,,,$],[$Total direct cost,,,,,,$]]$

d$-1.$ If the indirect costs for each project duration are $$400(18$ weeks$),$ $$350(17$ weeks$),$ $$300(16$ weeks$),$ $$250(15$ weeks$),$ $$200(14$ weeks$),$ and $$150(13$ weeks$),$ what is the total project cost for each duration?
