# If the coefficient for Activity 2 in the objective function changes to $400, then the objective function value

Using Fig 1.1 attached for remaining questions

4) If the coefficient for Activity 2 in the objective function changes to $400, then the objective function value:

a will increase by $7,500

b will increase by $2,750

c will increase by $100

d will remain the same

e can only be discovered by resolving the problem

5) If the coefficient for Activity 1 in the objective function changes to $50, then the objective function value

a will decrease by $450

b is $0

c will decrease by $2750

d will remain the same

e can only be discovered by resolving the problem

6) If the coefficient for Activity 2 in the objective function changes to $100, then

a the original solution remains optimal

b the problem must be resolved to find the optimal solution

c the shadow price is valid

d the shadow price is not valid

e none of the above

7) If the right hand side of resource b changes to $80, then the objective function value:
