8) The production planner for a private label soft drink maker is planning the
production of two soft drinks: root beer (R) and sassafras soda (S). Two resources are
constrained: production time (T), of which she has at most 12 hours per day; and
carbonated water (W), of which she can get at most 1,500 gallons per day. A case of
root beer requires 2 minutes of time and 5 gallons of water to produce, while a case of
sassafras soda requires 3 minutes of time and 5 gallons of water. Profits for the root
beer are $6.00 per case, and profits for the sassafras soda are $4.00 per case. What are
optimal daily profits?
A.$960
B.$1,560
C.$1,800
D.$1,900
E.$2,520

A.is parallel to the objective function.
B.has no coefficient for at least one decision variable.
C.has a zero coefficient for at least one decision variable.
D.has multiple coefficients for at least one decision variable.

19) The quality manager for Microelectronics, Inc., is concerned about the quality of
the batch of several thousand Z-box games which his company is about to ship. If the
cost of replacing a defective Z-box game once it has been shipped is $5.00, while the
cost of complete (100 percent) inspection prior to shipment is $.20 each, at what point
