Problem 3 The Lock and Co Hatters produces two types of hats, the panama hat and baseball cap. Each first type of hat which is the panama hat requires twice as much as labor time as the baseball cap. If all hats are baseball only, the company can produce a total of 500 hats a day. The market limits daily sales of the panama hat and baseball cap to 150 and 350 hats respectively. Assuming that the profits per hat are Rs. 8 for panama hat and Rs. 5 for baseball cap. Formulate the problem as a linear programming model in order to determine the number of hats to be produced of each type so as to maximize the profit.

Solve the optimization problem using linear programming. Find the optimal solution with graph.

Problem 3
The Lock and Co Hatters produces two types of hats, the panama hat and baseball cap. Each
first type of hat which is the panama hat requires twice as much as labor time as the baseball cap. If
all hats are baseball only, the company can produce a total of 500 hats a day. The market limits daily
sales of the panama hat and baseball cap to 150 and 350 hats respectively. Assuming that the
profits per hat are Rs. 8 for panama hat and Rs. 5 for baseball cap. Formulate the problem as a
linear programming model in order to determine the number of hats to be produced of each type so
as to maximize the profit.
