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) none of the above
