The sales department indicates that the sales potential for
products 1 and 2 exceeds the maximum production rate and that
the sales potential for product 3 is 20 units per week. The unit
profit would be $50, $20, and $25, respectively, on products 1, 2,
and 3. The objective is to determine how much of each product
Omega should produce to maximize profit.
(a) Formulate a linear programming model for this problem.
c (b) Use a computer to solve this model by the simplex method.
