READ* I keep seeing people but greater than and equal to as the answer and then I see less than and equal to as the answer... Which one is it. Please be 100% sure.

Suppose that you solve the LP relaxation of a production problem in which you are trying to minimize cost. The optimal value of the objective function is $250,000. You know that when you solve this problem as an integer program that the optimal solution will be 0 less than $250,000. 0 greater than $250,000 0 less than or equal to $250,000. greater than or equal to $250,000
