The Objective Function Coefficient for X₁ Is Currently $18 and for X₂

The objective function coefficient for X₁ is currently $18 and for X₂ is $29, and the ranges of optimality for these coefficients are between $15 and $20 and between $25 and $35, respectively.If the objective function coefficients for X₁ and X₂ decline by $2 each, since both coefficients are still within their ranges of optimality, the optimal solution is guaranteed to remain the same.
