A Max LP in $($as we will learn will be in pre$-$Big$-$M standard form$)$ starts with this initial non$-$simplex tableau.

we obtain

Setting the value of

equal to $1000,$ we must fix row$0$ by making

a basic variable $($pivot column$).$

What is the value of

in this initial simplex tableau?

Complete the simplex algorithm, what is the optimal value of

$?$
