1.A
A contractor can sell several classes of concrete at a different price per-ton for each class. The
materials specification for each class of concrete allows the percentage by weight of cement,
sand, and gravel to range between certain upper and lower bounds. The contractor knows
the unit cost (cost per-pound) to the company for each of the three components of concrete,
and how much of each component that is available for the company to purchase. The amount of
concrete of each type that the contractor can sell is limited but known. (Hint: This problem has a
maximization objective function, not minimization.)
