Linear Programming Problem Solution

Steps for Solving:

Step 1: Identify the Boundary Constraints of the Feasible Region:

Constraint 1: x+y250x + y \leq 250

Constraint 2: x80x \leq 80

Constraint 3: y40y \geq 40

Non-negativity constraints: x0,y0x \geq 0, y \geq 0

Step 2: Find the Intersection Points:

Determine the points where these constraints intersect to form the feasible region.

Step 3: Evaluate the Objective Function at Each Point:

Calculate the value of the objective function at each of these points to find the maximum.

Step 4: Choose the Point that Gives the Maximum Profit.

Solution:

Constraint 1: x+y250x + y \leq 250 (equivalent to x+y=250x + y = 250).

Constraint 2: x80x \leq 80 (this is a vertical constraint).

Constraint 3: y40y \geq 40 (this is a horizontal constraint).

Finding the Intersection Points:

Intersection of Constraint 1 and Constraint 2: 80+y=25080 + y = 250, hence y=170y = 170. Point: (80,170)(80, 170).

Intersection of Constraint 1 and Constraint 3: x+40=250x + 40 = 250, hence x=210x = 210. Point: (210,40)(210, 40).

Intersection of Constraint 2 and Constraint 3: x=80,y=40x = 80, y = 40. Point: (80,40)(80, 40).

Calculating the Objective Function at Each Point:

At (80,170)(80, 170): Z=0.2(80)+0.1(170)=16+17=33Z = 0.2(80) + 0.1(170) = 16 + 17 = 33.

At (210,40)(210, 40): Z=0.2(210)+0.1(40)=42+4=46Z = 0.2(210) + 0.1(40) = 42 + 4 = 46.

At (80,40)(80, 40): Z=0.2(80)+0.1(40)=16+4=20Z = 0.2(80) + 0.1(40) = 16 + 4 = 20.

Conclusion: The point (210,40)(210, 40) gives the maximum profit of 46. Therefore, invest $210 in A1A_1 and $40 in A2A_2 to achieve the maximum profit of $46.
