You formulate this as an assignment model and review the Zoe section of the sensitivity analysis with Mondo. Provide him with an interpretation

Answer: Zoe is assigned to wear the gown and will add 9 points to the overall fabulosity score. Even if Zoe's rating in the gown was up to 3 points lower, she would still be assigned to wear the gown. The overall score would be lower, but this would still be her assignment. Normally, the reduced cost entries speak to the change in objective coefficients before the assignment changes. As the model was presented, the coefficient for Zoe in the Leisure outfit was 4, with a reduced cost of -2, so a change in excess of 4 to 4- -2 = 6 would cause the Leisure outfit assignment to be optimal. As this is a balanced model, we cannot make that statement.
