Question $4$

Given the following optimal simplex table, which of the following statements is not correct?

$\backslash$table$[[\backslash$table$[[$Basic$],[$Variable$]],z,x_1,x_2,x_3,s_1,s_2,s_3,$soln.$],[z,1,4,0,0,1,2,0,1350],[x_2,0,-\frac{1}{4},1,0,\frac{1}{2},-\frac{1}{4},0,\backslash$table$[[100],[($operation$1)]]],[x_3,0,\frac{3}{2},0,1,0,\frac{1}{2},0,\backslash$table$[[230],[($operation$2)]]],[s_3,0,2,0,0,-2,1,1,\backslash$table$[[20],[($operation$3)]]]]$

Your answer:

A unit change in operation $1$ capacity changes $Z$ by $$1.$

A unit change in operation $2$ capacity changes $Z$ by $$2.$

A unit change in operation $3$ capacity changes $Z$ by $$4.$
