To solve this problem, we can use linear programming (LP) to determine how many sport coats and skirts the tailor should make in order to maximize profit while satisfying the material constraints and order requirements.

Step 1: Define the Variables

Let:

• $x$ be the number of sport coats to be made.
• $y$ be the number of skirts to be made.

Step 2: Define the Objective Function

The tailor sells each sport coat for $40 and each skirt for $45. Therefore, the total profit $P$ is: $P = 40x + 45y$ We aim to maximize this function.

Step 3: Define the Constraints

There are constraints based on the amount of available cotton and wool, as well as the minimum number of orders for sport coats and skirts:

• Cotton constraint: Each sport coat uses 2 square yards of cotton and each skirt uses 1 square yard. The tailor has 100 square yards of cotton, so the constraint is: $2x + y \leq 100$

• Wool constraint: Each sport coat uses 2 square yards of wool and each skirt uses 3 square yards. The tailor has 120 square yards of wool, so the constraint is: $2x + 3y \leq 120$

• Minimum order constraint: The tailor already has orders for at least 15 garments (sport coats and skirts combined). This leads to the constraint: $x + y \geq 15$

• Non-negativity constraint: The number of sport coats and skirts must be non-negative: $x \geq 0, \quad y \geq 0$

Step 4: Solve the Linear Programming Problem

Now, the problem is to maximize the profit $P = 40x + 45y$ subject to the following constraints:

2x + y & \leq 100 \\ 2x + 3y & \leq 120 \\ x + y & \geq 15 \\ x & \geq 0, \quad y \geq 0 \end{aligned}$$ We can solve this system graphically or using simplex method techniques. Would you like me to solve it step-by-step for you, or would you prefer a summary of the solution? --- ### Relative Questions: 1. What happens if the profit for sport coats increases? 2. How would additional cotton or wool material affect the production strategy? 3. What if the tailor receives additional orders beyond the 15 garments required? 4. How does the tailor's profit change if the cost of making garments increases? 5. Can the problem be solved using a different optimization method, such as integer programming? ### Tip: Linear programming is a powerful tool to optimize resource allocation problems, like production planning or financial portfolio management.
