Galaxy Candy Company manufactures two popular candy bars, the Eclipse bar and the Nova bar. Both candy bars go through a mixing operation where the various ingredients are combined, and the Coating Department where the bars from the Mixing Department are coated with chocolate. The Eclipse bar is coated with both white and dark chocolate to produce a swirled effect. A material shortage of an ingredient in the Nova bar limits

production to 300 batches per hour. Production and sales data are presented in the following table.
