Suppose that A equals 10. What are the values for (d1+) and(d1-) in the following constraint? A + (d1-) - (d1+) = 7

Group of answer choices

(d1-) =0, (d1+) =3

(d1-) =3, (d1+) =0

(d1-) =7, (d1+) =0

(d1-) =0, (d1+) =7

(d1-) =10, (d1+) =3

The optimal solution is to select only two of the alternatives.Suppose you wished to add a constraint that stipulated thatalternative 2 could only be selected if alternative 1 is alsoselected (i.e., if alternative 1 is not selected, you may notselect alternative 2; however, you may select #1 and not select#2). How would this constraint be written?

Group of answer choices

A - B = 0

A - B <= 0

A -B >= 0

A + B = 2

none of the above

A goal programming problem had two goals (assume equal weightsof 1). Goal number 1 was to achieve a cost of $2,400 and goalnumber 2 was to have no idle time for workers in the factory. Theoptimal solution to this problem resulted in a cost of $2,400 andno idle time. What was the value for the objective function forthis goal programming problem?
