Taking advantage of consumer weaknesses is what the Impulse Shopping Network does best. Onair hosts peddle each product during a predetermined period of time. During each segment (10 minutes maximum), viewers are enticed to whip out their credit card and order the product shown before the time runs out. These marketers are so convincing that even the savviest consumer cant avoid temptation. Moore Zales, Director of Marketing at Impulse Shopping Network needs to do some product planning for tomorrow evenings line-up. She needs to decide how to split the group of products being offered between an hour of peak and two hours of off-peak airtime in order to maximize the profits generated for the three-hour line-up. The following is a list of available items, their wholesale cost, retail price, stock-on-hand, and data on the quantity sold per minute in the previous week during both peak and off-peak times.
