Hi there could someone help me with this (if you could use paper to explain) thanks so much

(1) What is the total cost of the crashed project?

(2) Assume for this part only that the deadline to complete the project is 25 weeks and that you will incur a $200 per week penty thereafter. When should you stop crashing and what is the total cost of the project including penalties?

(3) Assume for this part only that there is a crashing budget of $200. What is the shortest amount of time the project can be completed in?

Example: Crashing
