Question

I just need the answers fo b, c, d

A firm uses three machines in the manufacture of three products. Each unit of product I requires 3 hours on machine 1, 2 hours on machine 2, and I hour on machine 3. Each unit of product:2 requires product 3 requires 2 hours on machine 1, 2 hours on machine 2, and 2 hours on machine 3. The contribution margin of the three products is $30, $40, and $35 per unit, respectively. Available for scheduling are 90 hours of machine 1 time, 54 hours of machine 2 time, and 93 hours of machine 3 time. 4 hours on machine 1, 1 hour on machine 2, and 3 hours on machine 3. Each unit of The linear programming formulation for this problem is: Maximize 30x,+40x +35x, subject to: +4x2 +2x3 3x +4x2 +2x 90 2x, +x2 +2x, 54 x +3x, +2x, 93 with x, x, x,20 The optimal tableau for the problem is already calculated for you as follows: RHS 1215 12 21 15 7.5 1/3 12.5 1/3 5/6 5/3 2/3 2/3 a) What is the optimal production schedule for this firm, meaning how many units of products 1, 2, and 3 should be produced? Are there any other optimal production schedules as indicated
