1. Consider corner pt. feasible A, B, C, D, E, F A: (0,0), Z = 0
B: (0,10), Z= 10
C: (5,10), Z= 20
D: (10,8), Z = 28
E: (13,5), Z= Optimal
F: (14.67,0), Z=29.33 18 12 10 5 C B D

2. True
True
False

3. B: Z=c1x1 + x2 = 5 > 0 regardless of c1
Max Z = c1x1 + x2
A: Z=c1x1 + x2 = 0
B: Z=c1x1 + x2 = 5 > 0 regardless of c1 6 5
C: Z=c1x1 + x2 = c > 5; c1 > 1/2 B
D: Z=c1x1 + x2 = c > c12 + 4; c1 > 1 C
- < c1 > ½, B is optimal
½ < c1 < 1, C is optimal
c1 > 1, D is optimal A D
