Problem $3(16$ pts$)$

Crash the network for minimum cost, and answer the questions below.

$\backslash$table$[[$Activity$,\backslash$table$[[$Normal$],[$Duration$]],\backslash$table$[[$Cost at Normal$],[$duration$]],\backslash$table$[[$Crash$],[$duration$]],\backslash$table$[[$Cost at crash$],[$duration$]]],[$A$,5,5,000,5,5,000],[$B$,8,6,000,3,18,000],[$E$,6,3,000,5,4,500],[$C$,2,1,000,2,1,000],[$D$,6,5,000,2,9,000],[$H$,5,2,000,4,3,000],[$F$,7,18,000,3,20,000],[$G$,5,1,000,3,4,000],[$K$,8,15,000,8,15,000]]$

$(6)$ Answer the following. Show how you calculate each.

What is the normal project duration?

What is the MINIMUM project cost for the NORMAL project duration?

What is the MAXIMUM project cost for the NORMAL project duration?

What is the crash project duration?

What is the MINIMUM project cost for the CRASH duration?

What is the MAXIMUM project cost for the CRASH duration?

$5000+6000+5000+18000+15000=49000+4500+1000+3000+3000+4000$
