Question 1
A linear programming problem contains a restriction that reads "the quantity of Q must be no larger than the sum of R, S, and T." Formulate this as a constraint ready for use in problem solving software.
◦ Q ≥ R + S + T
◦ Q - R - S - T ≤ 0
◦ Q / (R + S + T) ≤ 0
◦ Q × (R + S + T) ≤ 4
◦ Q + R + S + T ≤ 4
Question 2
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.
◦ 4S ≤ T + U
◦ S ≥ 4T / 4U
◦ S - .25T - .25U ≥ 0
◦ S / (T + U) ≥ 4
◦ S × (T + U) ≤ 4
