1. How much slack does activity F have?

2. Use image above as needed

Consider the following construction project break-down: Suppose that the goal is to reduce the project duration to 16 days. Explain, step by step, which tasks to crash, and compute the resulting total cost of reducing the project duration to 16 days. \begin{tabular}{cccccc} \hline Activity & NormalTime(days) & CrashTime(days) & NormalCost($) & CrashCost($) & DailyCrashCost($) \\ \hline A & 4 & 1 & 100 & 1000 \\ B & 7 & 5 & 200 & 400 \\ C & 6 & 3 & 150 & 390 \\ D & 2 & 1 & 100 & 150 \\ E & 4 & 2 & 500 & 900 \\ \hline \end{tabular}
