Formulate and solve the following linear program. A firm wants to determine how
many units of each of two products (products D and E) they should produce to make the
most money. The profit in the manufacture of a unit of product D is $100 and the profit
in the manufacture of a unit of product E is $87. Although the firm can readily sell any
amount of either product, it is limited by its total labor hours and total machine hours
available. The total labor hours per week are 4,000. Product D takes 5 hours of labor
per unit and product E takes 7 hours of labor per unit. The total machine hours are
5,000 per week. Product D takes 9 hours of machine time per unit and product E takes 3
hours of machine time per unit. Write the constraints and the objective function for this
problem, solve for the best mix of product D and E and report the maximum value of
the objective function?
