1. The reduced cost (shadow price) for a positive decision variable is
0. Answer: TRUE
Diff: 2 Page Ref: 90
Main Heading: Computer Solution
Key words: shadow price, sensitivity analysis


2. When the right-hand sides of 2 constraints are both increased by 1 unit, the value of
the objective function will be adjusted by the sum of the constraints' prices.
