3. A company manufactures two types of products: A and B. Three resources R1, R2, and R3 are required to make these products. a.

mojhsa [17]

Answer:

(i)The units of production of Product A and B (x and y) are the decision variables

(ii)Objective is to maximize profit

(iii)Objective function, Max P=20x+50y

(iv)The Contraints are:

8x+2y $\leq$ 500....(i)

2x+5y $\leq$ 400.......(ii)

3y $\leq$ 180

x>0, y>0

Explanation:

Let the number of Product A=x

Let the number of Product B=y

Each unit of product A requires 8 units of R1 and 4 units of R2.

Each unit of product B requires 2 units of R1, 5 units of R2, and 3 units of R3

The availabilities of resources R1, R2, and R3 are 500, 400, and 180

Since R1 $\leq$ 500,

Product A requires 8 units of R1 per production unit

Product B requires 2 units of R1 per production unit

Total Unit of R1 possible is given by the inequality: 8x+2y $\leq$ 500....(i)

Since R2 $\leq$ 400,

Product A requires 2 units of R2 per production unit

Product B requires 5 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 2x+5y $\leq$ 400....(ii)

Since R3 $\leq$ 180,

Product B requires 3 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 3y $\leq$ 180....(iii)

Since the manufacturer also makes a profit of $20 and $50 for products A and B, our objective is to maximize profit

Therefore: Objective function, Max P=20x+50y ......(iv)

Answer:

C. Recorded using a Create Invoices window
