(a) Explanation Given: A farmer has 100 acres of land for harvesting. It costs $400 to produce an acre of potatoes, $160 to produce an acre of corn, and $280 for an acre of cabbage. He can invest no more than $20,000 on harvesting. He makes a profit $120 per acre of potatoes, $40 per acre of corn, and $60 per acre of cabbage. Explanation: Let the farmer grow x 1 acres of potatoes, x 2 acres of corn, and x 3 acres of cabbage. Then the provided statements would convert into the system of linear inequalities: x 1 + x 2 + x 3 ≤ 100 400 x 1 + 160 x 2 + 280 x 3 ≤ 20 , 000 Also, x 1 , x 2 , x 3 ≥ 0 where the objective function to be maximized is z = 120 x 1 + 40 x 2 + 60 x 3 . Use the above information to form this matrix: [ 1 1 1 100 400 160 280 20 , 000 120 40 60 0 ] _ . Transpose this to obtain a dual matrix [ 1 400 120 1 160 40 1 280 60 100 20 , 000 0 (b) To determine The profit earned by the farmer if the land is cut to 90 acres, but capital increases to $21,000. (c) To determine The maximum profit earned by the farmer and the planting strategy that will produce this profit.
