Consider the constraint X₃ + X₄ + X₅ + X₆ + X₇ ≥ 27 Representing Air Express' Monday minimum worker requirement. Why was a "≥" used versus an "="? A) The "≥" is needed to accommodate workers held over from Sunday. B) Solver only accepts "≥" constraints. C) The "≥" is less restrictive. D) The "=" will always produce an infeasible constraint.

The "≥" is less restrictive than "=" because it allows for more possible solutions. In this case, it means that Air Express can have more than 27 workers on Monday if necessary, but must have at least 27. An "=" would require exactly 27 workers, which could be too limiting and may not be feasible in certain situations.
