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:

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.

answer; ///i believe that the correct answer is (post conventional)

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
