can someone fix this!

Question 1 (45 points). Table below contains information about an environmental clean-up project in the township of Hiles. Shorten the project three weeks by finding the minimum-cost schedule. Assume that project indirect costs and penalty costs are negligible. Identify activities to crash while minimizing the additional crash costs. Table 1 - Environmental Project Data Activity Normal Time Crash Time Cost to Crash Immediate (weeks) (weeks) (s per week) Predecessor(8) A 7 200 None 12 250 None 6 B 9 7 6 250 A D 6 5 300 A E 1 B F 1 1 CD 3 1 200 DE H 3 2 350 F 1 2 2 G 7 7 F END D START 3 G 21 B = 18 There are two possible critical path given below with their duration Pathl: A-D-G-I = 7+6+3+2 Path 2: B-E-G-I = 12+1+3+2= 18 There are two activities that have minimum crashing costi.c.activity A from path I and Activity G from path 2 with a minimum crash cost equal to $200 From Table, Activity A can be crashed by 1 week so the total crash cost - $200 reducing the critical path 1 to 18-1-17 Now the critical path will be B-E-G-I. In this activity, G has the least cost of crash Now activity can be crashed by I week and total crashing cost will be $200+$200 5400 Again there will be two critical paths A-D-G-I and B-E-G-I with duration 17 weeks, now we can only crash activity G as it has minimum crash es and can be crashed by one more week so total crashing cost- $400+$200 $600 and total project duration after crashing=16 weeksSo for crashing the project by 3 weeks, we will crash activity A and G by 1 week and 2 weeks respectively and total crashing cost will be S600 . Question 1. There are more than 2 critical paths in the beginning. After the first set of activities are crashed, there are more than 1 and 2 critical paths, respectively in the following steps as well . The number of critical paths would have an impact on which activities to crash, so please take a look at that question again
