Answer this question with respect to the CONSULTANT PROBLEMposted in Canvas (Test 6 Output document above).Any proposed changes to the CONSULTANT PROBLEM pertain only to that problem. Do not carry forward changes made in one problem to another problem. Assume that Client C suddenly increases the number of required hours from 100 to 140. In solving the CONSULTANT PROBLEM, which of the following statements becomes true?

Group of answer choices

The profit from the Baker-Client C arc changes now in the objective function.

A dummy supply node with a supply of 140 hours will have to be added.

A dummy supply node will have to be added. The dummy supply (= node 4) will have a total supply of 20 hours.

Nothing changes. The old optimal solution is still valid.

2. THE CONSULTANT PROBLEM on your test is based on Problem 5: Page 293 from the book. The INITIAL problem network is shown below for your convenience. On your test, some of these problem parameters may be changed. PLEASE ALSO REFER TO THE PROBLEM ON PAGE 293 OF THE BOOK TO GET THE FULL PICTURE AND TO BE ABLE TO ANSWER ALL QUESTIONS ON THE TEST. WE WILL CALL THIS PROBLEM THE CONSULTANT PROBLEM ON YOUR TEST. IN ANSWERING THIS QUESTION ASSUME THAT: Avery = Supply Node 1, Baker = Supply Node 2, Campbell = Supply Node 3. If a dummy supply node is ever added, it becomes supply node 4. Client A = Demand node 1, Client B = Demand node 2, Client C = Demand 3, Client D = Demand 4. So the objective function coefficient on flow arc X23 = 115. Demand - 180 160 Avest d = 75 5 5 160 client B Bake $ 2= 100 Client C Campbell Cost of from Baker to Clientcells DAMDOO PAPER 2
