The company makes two types of sausages:

  • Economy (>=40% Pork)

  • Premium (>=60% Pork)

One sausage is 50 grams (0.05 kg)

According to government regulations, the most starch we can use in our sausages is 25%

We have a contract with a butcher, and have already purchased 23 kg pork, that will go bad if it’s not used.

We have a demand for 350 economy sausages and 500 premium sausages.

Write a linear program to figure out the most cost-effective recipe to manufacture our sausages.
