Problem 7-21

For the linear program:

Please help I don't understand how to do these calculations and I am trying to study.

Max		2A	+	3B
s.t.
		5A	+	5B		400
		-1A	+	1B		10
		1A	+	3B		90
				A, B		0

Select the constraint represented by each constraint line (1, 2, or 3). Constraint 1 =

Constraint 2 =

Constraint 3 =

Identify the optimal extreme point. What is the optimal solution? Optimal solution is A = fill in the blank, B = fill in the blank , Max = fill in blank Select the correct graph that shows the optimal solution for the problem.

Identify the optimal extreme point. What is the optimal solution? Optimal solution is A = fill in the blank 5, B = fill in the blank 6, Max = fill in the blank 7

Which constraints are binding? Constraint 1 =

Binding or Non-binding

Constraint 2 =

Binding or Non-binding

Constraint 3 =

Binding or Non-binding

How much slack or surplus is associated with the nonbinding constraint?
