2. In an optimization model, x and y are the two decision variables. One constraint in the optimization model is X+Y>100. If the right hand side of this constraint increases from 100 to 101, i.e., the new constraint becomes X+Y>101, what can you say about the new optimal solution? Explain.

leads a better result/objective

leads a worse or the same result/objective

leads a better or the same result/objective
