Question 2 .2 out of 2 points In a balanced transportation model‚ supply equals demand such that all constraints can be treated as equalities. Answer Selected Answer: True Correct Answer: True . Question 3 .2 out of 2 points In a transportation problem‚ a demand constraint (the amount of product demanded at a given destination) is a less-than-or equal-to constraint (≤). Answer Selected Answer: False Correct Answer: False . Question 4 .2 out of 2 points

maximize utility‚ denoted U (x‚ y). Her problem is then to Maximize: U = U (x‚ y) subject to the constraint B = p x x + py y Unless there is a Corner Solution‚ the solution will occur where the highest indifference curve is tangent to the budget constraint. Equivalent to that is the statement: The Marginal Rate of Substitution equals the price ratio‚ or px M RS = py This rule‚ combined with the budget constraint‚ give us a two-step procedure for finding the solution to the utility maximization problem.

All points to the interior of the budget constraint are affordable. II. All points that lie on the budget constraint cost the same amount of money. Response: Both I and II are false. * Edit Question 4 Shiela is maximizing her utility. Her MUx/Px=10 and MUy=40. Then the price of Y must be Response: 40 * Edit Question 5

of the port. This meant that for each route‚ each price or quantity was subject to an individual constraint‚ and all the other ten routes were not tied to each other in any way. the new pricing model proposed‚ takes into consideration that there is no individual constraints but rather an overall constraint which is the weight and volume of the ship travelling those routes‚ so within those constraints what dictates price is the demand. It was clearly stated that 40’ containers were not only preferred

goal is to maximize total profit. In constructing a model‚ the first step is to define the decision variables; the next step is to write the constraints and objective function in terms of these variables and the problem data. In the problem statement‚ phrases like "at least‚" "no greater than‚" "equal to‚" and "less than or equal to" imply one or more constraints.

when all of the constraints in the problem have or = constraints‚ a starting basic feasible solution may not be readily apparent. The Big M method is a version of the Simplex Algorithm that first finds a basic feasible solution by adding "artificial" variables to the problem. The objective function of the original LP must‚ of course‚ be modified to ensure that the artificial variables are all equal to 0 at the conclusion of the simplex algorithm. Steps 1. Modify the constraints so that the RHS of
