Question $4$

$1$ points

Two models of a product $-$ Regular $(x)$ and Deluxe $(Y)-$ are produced by a company. A linear programming model is used to determine the production schedule. The formulation is as follows:

Maximize profit $=50x+60Y,$

Subject $to$: $8x+10Y800(labor$ hours$)$

$,x+Y120(total$ units demanded$)$

$,4x+10Y500(raw$ materials$)$

$,x,Y0,$

The optimal solution is $x=100,Y=0.$

Which of these constraints is redundant?

the first constraint

the second constraint

the third constraint

All of these

None of these
