Acardboard box supplier must deliver 3,000 size large boxes per week to keep its largest customer happy. the process for manufacturing the box is a four-step serial process and because they use recycled material, material quality is sometimes compromised resulting in scrap at each step. the scrap (defect) rates for the four respective steps are as follows: d1=0.07, d2=0.04, d3=0.05, and d4=0.02. how many boxes need to be started each month to meet the desired demand.
