Consider a chocolate manufacturing company that produces only two types of chocolate A and B$.$ Both the chocolates require Milk and Choco only. To manufacture each unit of A and B$,$ the following quantities are required: Each unit of A requires $1$ unit of Milk and $3$ units of Choco. Each unit of B requires $1$ unit of Milk and $2$ units of Choco.The company kitchen has a total of $5$ units of Milk and $12$ units of Choco. On each sale, the company makes a profit of RS $6$ per unit A sold. RS $5$ per unit B sold. Now, the company wishes to maximize its profit. How many units of A and B should it produce? Q$1-$ Identify the decision variables? Q$2-$ Write the objective function? Q$3-$ Identify the constraints? Q$4-$ Find the optimal solution and the optimal value using the Graphical Analysis.
