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 eight-hour 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 200 units. All units produced can be sold. The cost of operating
the photo production department four more hours each day is $1310. The contribution
margin of the finished products is $20 each.
What is the change in the daily contribution margin if the change is made?
A) $250
B) $2690
C) $4000
D) $200
