#$8$ Problem $17-15($Static$)$

A construction project has indirect costs totaling $$40,000$ per week. Major activities in the project and their expected times in weeks are shown in this precedence diagram.

a$.$ Determine the optimum time$-$cost crashing plan. Continue crashing as long as the total crashing cost at each step is less than or equal to $$40.$

Week $1$:

Week $2$:

Week $3$:

Week $4$:

Week $5$:

$^^^$ It is making me pic an answer for each week from a drop$-$down menu. The options are each activity $($e$.$g$.7-11,1-2,2-5,11-13$ & $4-6,7-11$ & $6-10).$ These options also include $"$Do not crash".

b$.$ Compute total crashing cost and total indirect costs.

Note: Enter numbers in the same format as the crashing cost table, i$.$e$.,$ enter $25$ instead of $25,000.$

Total crashing costs:

Total indirect costs:
