QUESTION $7$

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$)$

$4x+5Y500(raw$ materials$)$

all variables $0$

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

How many units of the regular model would be produced based on this solution?

A$.0$

B$.100$

C$.50$

D$.120$

E$.$ None of the above
