1. What is the expected project duration before crashing any activities ? 2. What is the cost of the third crash ? 3. what is the cost of the sixth crash ? 4. What is the total cost of all crashes that should be done to minimize cost ?

5. How much should be spent on penalties?

Chuck's Custom Boats (CCB) builds customer luxury yachts. CCB has landed a contract with a mysterious New York real estate developer, Mr. T. Relevant data on the project are shown below. The complication is that Mr. T wants delivery in 30 weeks or he will impose a penalty of $250 for each week his yacht is late. Determine the lowest cost plan for crashing this project. Note: All numbers are in thousands, but keep them that way (i.e., don't enter the last three zeros). What is the expected project duration before crashing any activities?
