Use the information provided in the Table 1 and the network diagram in Figure 1 for the following problems.

Activity	Normal Time(weeks)	Normal Cost ($)	Crash Time (weeks)	Crash Cost ($)	Maximum weeks Reduced	Crash Cost per Week ($)
A	4	550	3	950	2	450
B	5	650	4	750	2	150
C	7	850	4	1350	4	550
D	7	1550	5	2200	3	100
E	7	1800	5	2300	3	550
F	6	250	6	1250	1	1050
G	8	1550	6	1850	3	350

1. Using the information given,
   • Calculate the completion time of the project.
   • Identify the activities on the critical path.
2. Using the information given and the project completion time calculated in Problem 1, reduce the completion time of the project 3 weeks in the most economical way.
3. Using the information given and the project completion time calculated in Problem 1, calculate the minimum time for completing the project possible.

UPDATE: Activity H is simply the last activity on the diagram. I am told you don't need it to actually compute anything or create formulas, but it's needed when counting the number of weeks.
