multiple choice $1$

A$-$C$-$F$-$G

A$-$D$-$F$-$G

A$-$D$-$E$-$G

A$-$B$-$E$-$G

c$.$ Compute the minimum total direct cost for each project duration based on the cost associated with each activity. Consider durations of $13,14,15,16,17,$ and $18$ weeks.

Note: Leave no cells blank $-$ be certain to enter $"0"$ wherever required.

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?

d$-2.$ Indicate the minimum total project cost duration.

multiple choice $2$

$16$ or $15$ weeks

$14$ or $15$ weeks

$13$ weeks

$17$ weeks
