Multiple Choice

Below are the data for a Time-Cost CPM Scheduling model analysis.The time is in days and the costs include both direct and indirect costs. $\begin{array}{|l|l|l|l|l|l|}\hline & \text { Immediate } & \text { Normal } & \text { Crash } & \text { Normal } & \text { Crash } \\\hline \text { Activity } & \text { Predecessor } & \text { Time } & \text { Time } & \text { Cost } & \text { Cost } \\\hline \text { A } & \text { None } & 3 & 2 & \$ 200 & \$ 400 \\\hline \text { B } & \text { A } & 4 & 3 & \$ 300 & \$ 600 \\\hline \text { C } & \text { A } & 1 & 1 & \$ 300 & \$ 300 \\\hline \text { D } & \text { B and C } & 3 & 2 & \$ 500 & \$ 550 \\\hline \text { E } & \text { D } & 2 & 1 & \$ 500 & \$ 900 \\\hline\end{array}$
