The Vallence Cheese Company of Warrnambool produces two cheese spreads by blending mild cheddar with sharp tasty cheddar. The spreads are packaged in jars of 300 gram net and distributed. The Standard spread contains 80% mild cheddar and 20% sharp tasty cheese whereas the Extrabite spread contains 60% mild cheddar and 40% sharp tasty cheese. Given 600 kg of mild cheddar and 330 kg of extra tasty cheese are available this month, and jars of both spreads sell for $ 4 each, formulate the LP and sketch the feasible region.
