1. If sensitivity analysis shows an allowable increase of infinity for the objective coefficient range for variable x1, it means

1. The problem is unbound

2. The value of x1 can increase without limit

3. The objective function coefficient for x1 can increase without limit and variables will all have the same optimal values

4. The objective function coefficient for x1 can increase without limit and all the variables except x1 will change their optimal value

2. The objective function Max 14x1 + 19x2 reflects the relevant cost of labor hours used in production. The correct interpretation of shadow price associated with the labor hours constraint is

1. The maximum premium over the normal price (say for overtime) the company would be willing to pay.

2. The upper limit on the total hourly wage the company would be willing to pay

3. The reduction in hours that could be sustained before the solution would change

4. All of the above

5. None of the above

3. Suppose the shadow price for resource 1 in an LP problem is 22. Also, consider that the constraint that establishes the resource requirement is a "less than or equal to" type constraint. As such, there is no slack ( or "zero" value for slack) associated with the constraint of resource 1.

1. true

2. false
