Assume that Melesha Electronics must determine how many LCD TVs and Sound System Players to stock. It costs Melesha Birr 13,000.00 to purchase a LCD TV and Birr 12,000.00 to purchase a Sound System Player. A LCD TV requires 3 square yards of storage space, and a Sound System player requires 2 square yard. The sale of a LCD TV earns Melesha a profit of Birr 1,500.00, and each Sound System Player sale earns a profit of Birr 1,000. Melesha has set the following goals (listed in order of importance):

• Goal 1: A maximum of Birr 2,000,000.00 can be spent on purchasing LCD TV s and Sound System players.
• Goal 2: Highland should earn at least Birr 185,000.00 profit from the sale of LCD TV s and Sound System Players.
• Goal 3: LCD TVs and Sound System Players should not use up more than 200 square yards of storage space.

Use a goal programming model to determine how many LCD TVs and Sound System Players Melesha should order. How can you modify the model if Melesha 's second goal is to have a profit of exactly Birr 185,000.00?
