* A linear program has the objective of maximizing profit = 12X + 8Y. The maximum profit is $8,000. Using a computer we find the upper bound for profit on X is 20 and the lower bound is 9. Discuss the changes to the optimal solution (the values of the variables and the profit) that would occur if the profit on X were increased to $15. How would the optimal solution change if the profit on X were increased to $25?
* It has been said that each LP problem that has a feasible region has an infinite number of solutions. Explain why this is true.

FOR MGMT 205 * I DO NOT WANT AN ANSWER THAT TALKS ABOUT TOBACCO OR BONDS** Your problem will have exactly two variables (an X1 and an X2) and will incorporate a maximization (either profit or revenue) objective. You will include at least four constraints (not including the X1 ? 0 and X2 ? 0 [i.e., the “Non-negativity” or “Duh!”] constraints). At least one of these four must be a “?” constraint, and at least one other must be a...
