A company produces two products, A and B. Product A takes 1 hour to produce and costs
$2 to produce. Product B takes 2 hours to produce and costs $3 to produce. The company
has 10 hours of time available and $20 available to spend on materials. The company wants
to find the number of products A and B to produce that will minimize the cost of production
and maximize profits. What is the optimal quantity of products A and B that the company
should produce?
Let x = number of product A, y = number of product B, and z = cost of production
What is the objective function of the problem?
Z= 2X =3Y
Which of the following is not a constraint?
X,Y<0
What is the optimal quantity of products A and B that the company should produce?
4. Prod A , 2 Prod B
