1. Using the network diagram and the additional information below,find
   1. The crash cost perday
   2. Which activities should be crashed to meet a project deadline of 13 daysat minimum cost. Assume partial crashing isallowed.

1. Reconsider Question 2 above, assuming a fixed overhead cost of $30 per day but no project deadline. What is the leastcost crash program? What if the overhead costwas

$40? What if it was $60?

Activity| Crash Time (days)|Crashed Cost (total) [Normal Time (days) Normal Cost A 3 $500 4 $300 B 1 925 3 250 C 4 550 7 400 D 3 250 5 150
