Question
The landlord uses the following scheme for decision variables:| x1 = contractor works on wood floors | x2 = landlord works on wood floors |
| x3 = contractor works on kitchen tile | x4 = contractor works on kitchen tile |
| x5 = contractor works on back door | x6 = contractor works on back door |
| x7 = contractor works on garage door | x8 = contractor works on garage door |
What should the objective function be?
A) Min Z = 2700x1 + 400x2 + 2500x3 + 1000x4 + 600x5 + 250x6 + 350x7 + 400x8
B) Min Z = 2700x1 - 400x2 + 2500x3 - 1000x4 + 600x5 - 250x6 + 350x7 - 400x8
C) Max Z = 100x1 + 100x2 + 80x3 + 80x4 + 15x5 + 15x6 + 20x7 + 20x8
D) Max Z = 100x1 - 100x2 + 80x3 - 80x4 + 15x5 - 15x6 + 20x7 - 20x8
