The corner point where the Mixing Dept. and Baking Dept. constraints intersect can be calculated as (18, 8) by so lving: 30D + 15B = 660 (1) Mixing Dept. constraint 10D + 15B = 300 (2) Baking Dept. constraint Subtracting (2) fro m (1), we have 20D = 360 or D = 18 Subst ituting in (2) (10 ´ 18) + 15B = 300 that is, 15B = 300 - 180 = 120 o r B = 8 The corner point where the Filling and Baking Department constraints intersect can be calculated as (3,18) by subst ituting B = 18 (Filling Department constraint) into the Baking Department constraint: 10 D + (15 ´ 18) = 300 10 D = 300 - 270 = 30 D = 3 The feasible regio n, defined by 5 corner po ints, is shaded in So lution Exhibit 11­40.
