The worth of this variable will be positive at one of the various other optimal corners.”

Can lessened expense be negative?

The lessened price of an easy variable is always zero (because you need not change the objective function at all to make the variable positive). If the final worth is zero, then the lessened cost is negative one times the allowable boost.
