1. A constraint with a positive surplus:

a. has no restrictions for its dual price.

b. will have a negative dual price.

c. will have a positive dual price.

d. will have a dual price of zero.

e. is called a binding constraint.

2. A negative dual price for a constraint in a minimization problem means

a. as the RHS of the constraint increases by one unit, the objective function value (OV) will decrease.

b. as the RHS of the constraint increases by one unit, the objective function value (OV) will increase.

c. as the RHS of the constraint increases by one unit, the objective function value (OV) will decrease.

d. as the RHS of the constraint decreases by one unit, the objective function value (OV) will decrease.
