$5A+5B380$ Constraint $1$

$-1A+1B10$ Constraint $2$

$1A+3B90$ Constraint $3$

$A,B0,$

The figure shows a graph of the constraint lines.

$($c$)$ Identify the optimal extreme point. What is the optimal solution?

$(A,B)=(,)$

$($d$)$ Which constraints are binding? Explain.

The optimal solution occurs at the intersection of constraints $---$Select$---,$ so these are the binding constraints.

$($e$)$ How much slack or surplus is associated with the nonbinding constraint?

Constraint $|$ is the nonbinding constraint. There is a

of

associated with this constraint.
