Richards agreed to list his property for sale with Broker Jackson. In using a standard listing form, Richards completed Paragraph 10 with the following words: "Delete provisions in Paragraph 3c above which says, Agency is hereby authorized to accept on my behalf a deposit toward the purchase price in any amount." If Broker Jackson produced a buyer:

A: He cannot accept a deposit from the buyer; B: He must get oral permission from Richards before accepting a deposit; C: If he accepts a deposit, he holds it as agent of the buyer until the offer is accepted by the seller; D: If he accepts a deposit from the buyer and the buyer rescinds the offer prior to acceptance by the seller, he is entitled to one-half of the deposit.

A manufacturer builds finished items A, B, and C from five different components. They currently have several finished units, a number of items that are partially complete, and many components that have just been delivered from their suppliers

The finished items, incomplete items and raw components can all be assigned some monetary value even though the manufacturer typically does not sell anything except finished items. The manufacturer needs to raise capital quickly so they formulate a linear program to help them decide on the most profitable way ahead. Their linear programming expert forgets to restrict their decision variables to non-negative values and is surprised when the computer output tells them that finished item A and C should be negative. If the company always follows the advice of their linear programming analysis, what should they do and why?
