Consider the linear program given below $($almost the same as the previous problem $-$ the only difference is that the right hand side of the first constraint has been increased from $10$ to $11)$:

Decision variables: $A,B,C,$ and $D$

Objective: maximize $3A+5B+10C+2D$

Constraints:

$A+B+C+D11$

$A-B=0$

$A+B-C-D0$

function value, NOT the new value of the objective function. As before, please assume that all variables are non$-$negative$)$
