A linear programming problem contains a restriction that reads "the quantity of S must be no less than one-fourth as large as T and U combined." Formulate this as a constraint ready for use in problem solving software.
A) S / (T + U) ≥ 4
B) S - .25T - .25U ≥ 0
C) 4S ≤ T + U
D) S ≥ 4T / 4U
E) S × (T + U) ≤ 4

The constraint is stating that S must be greater than or equal to one-fourth of the sum of T and U. We can translate this into mathematical notation as S - 1/4(T + U) ≥ 0. Simplifying this expression, we get S - 0.25T - 0.25U ≥ 0, which is equivalent to choice B.
