2. A Corporation has decided to produe three new products. Five branch plants now have excess production capacity. The unit manufacturing cost of the first product would be $31,$29,$32, $28, and $29 in Plants 1,2,3,4, and 5, respectively. The unit manufacturing 1 cost of the second product would be $45,$41,$46,$42, and $43 in Plants 1,2,3,4, and 5 , respectively. The unit manufacturing cost of the third product would be $38,$35, and $40 in Plants 1, 2, and 3, respectively, whereas Plants 4 and 5 do not have the capability for producing this product. Sales forecasts indicate that 600,1000 , and 800 units of products 1, 2, and 3, respectively, should be produced per day. Plants 1,2,3,4, and 5 have the capacity to produce 400,600,400,600, and 1000 units daily, respectively, regardless of the product or combination of products involved. Assume that any plant having the capability and capacity to produce them can produce any combination of the products in any quantity. (a) (points: 9) Formulate this problem as a balanced transportation problem by constructing the representation table. (b) (points: 4) Find an initial basic feasible solution by the northwest corner rule. Show the intermediate steps
