BUS 461 Week 2 Quiz

1. Question : The functional constraints of a linear model with nonnegative variables are 3X1 + 5X2 = 16 and 4X1 + X2 = 10. Which of the following points could not be an optimal solution for the model?

Student Answer: X1 = 2.5, X2 = 0

X1 = 0, X2 = 3.2

X1 = 1, X2 = 2.25

X1 = 2, X2 = 2

7. Question : Linear programming models are a subset of constrained optimization models that require the assumptions of continuity of the variables, certainty of the coefficients, additivity of terms, and proportionality of costs, profits, and the use of resources to the value of the decision variables.
