Suppose That the First Goal in a GP Problem Is

Multiple Choice

Suppose that the first goal in a GP problem is to make 3 X₁ + 4 X₂ approximately equal to 36. Using the deviational variables d₁− and d₁⁺, what constraint can be used to express this goal?

A) 3 X₁ + 4 X₂ + d₁− − d₁⁺ ≤ 36
B) 3 X₁ + 4 X₂ − d₁− − d₁⁺ = 36
C) 3 X₁ + 4 X₂ + d₁− + d₁⁺ = 36
D) 3 X₁ + 4 X₂ + d₁− − d₁⁺ = 36
