What does the non-negativity condition x ≥ 0 and y ≥ 0 mean in a linear programming model?
Correct answer: B. The variables cannot take negative values
- A. The variables must have equal values
- B. The variables cannot take negative values
- C. The variables must be whole numbers
- D. The variables must remain below one
Explanation
Non-negativity restricts each decision variable to zero or a positive value. It does not require variables to be integers, equal, or less than one.
