a.
To formulate: A linear programming model.
Introduction: The linear programming model is used to minimize the cost and maximize the profit through algebraic and graphical presentation using different variables and satisfying them.

Explanation of Solution
Given information:
Company TM wants to maximize cakes and loaf of breads and is willing to sell a cake for $10 and a loaf of bread for $6.
The coordinates for the above equations are:
Table (1)
By solving the above equations, the values of
Table (2)
The graphical analysis is as follows:
Fig (1)
A feasible solution (ABCD) where objective function is at its maximum point is known as optimal solution. At this point, no other feasible and better solution exists. This point exists either at the top or at bottom as per the requirement of objective function and its constraints.
Therefore, the optimal solution is point C
