A constraint with a positive slack value will have a positive dual price. will have a negative dual price. will have a dual price of zero. has no restrictions for its dual price.

will have a dual price of zero

Explanation:

In a problem relating to optimization, a slack variable is simply referred to a variable which can be added to the inequality constraint so that it'll be changed to an equality.

It should be noted that when a slack variable is introduce, the inequality constraint will have to be replaced by an equality constraint. A constraint with a positive slack value will have a negative dual price of zero.

will have a dual price of zero.

Explanation:

Slack variables are used in linear programming equation where the equation is not balanced and to balance the equation a variable equal to zero is introduced called a slack variable.

The constraint in the slack variable will be zero, where the positive value.

It is never equal to zero, but the value is so low and so near to zero that it is considered to be equal to zero.
