Hint: In order to be successful in this activity you must draw out the AON diagram on your own in order to best answer the following questions.

What is the most economical way to reduce the project time $($crash$)$ by $2$ days

Question $15$ options:

P$-$$$200,$ U$-$$$150$

Does not matter as long as you crash by $2$ days,

L$-$$$100,$ I$-$$$150$

L$-$$$100$

None of these are correct.

L$-$$$200$

K$-$$$500$

I$-$$$300$
