Given the following LP model, using Solver

Min 3S + 9C

s.t.

6S + 10C <=60

7S + 5C <= 42

X , Y >= 0

a. What is the optimal value of the objective function?

b. What are the optimal values of the two decision variables?

c. Find the range of optimality for objective function coefficients S and C.

d. How would a decrease of 1 gram in the S coefficient of the objective function affect the optimal values of the decision variables?

e. What is the range of feasibility of the dual value for the RHS of S and C?

Solutions

Expert Solution

(a)

Min. Objective =0

(b)

S=0; C=0

Sensitivity report

(c)

The coefficient of S: [0, inf)
The coefficient of C: [0, inf)

(d)

No change in the objective would happen because the change is within the range of optimality.

(e)

Constraint 1 range: [0, inf)
Constraint 2 range: [0, inf)
