Captain Carl's Seascapes produces sea pictures for sale through catalogs. The company has two workstations, photo production and framing. The photo production station is limited by the speed of operating the photo development machine. Framing is limited by the speed of the employees. Framing normally waits for work from photo production. Each department works an eightminushour day. If Captain Carl's Seascapes adds an earlier half shift so that photo production begins work four hours earlier than framing each day, the two departments generally finish their work at about the same time. Not only does this eliminate the bottleneck, but it also increases finished units produced each day by 300 units. All units produced can be sold. The cost of operating the photo production department four more hours each day is $ 1 comma 310. The contribution margin of the finished products is $ 12 each. What is the change in the daily contribution margin if the change is made?
