Highland’s TV-Radio Store must determine how many TVs and radios to keep in stock. A TV requires 10 sq ft of floor space, whereas a radio requires 4 sq ft; 200 sq ft of floor space is available. A TV will earn Higland $60 in profits, and a radio will earn $20. The store stocks only TVs and radios. Marketing requirements dictate that at least 60% of all appliances in stock be radios. Finally, a TV ties up $200 in capital, and a radio, $50. Highland wants to have at most $3000 worth of capital tied up at any time
