Convert the Objective Function into a Maximization Function $\mathrm{w}=2 \mathrm{y}_{1}+\mathrm{y}_{2}+3 \mathrm{y}_{3}$

Multiple Choice

Convert the objective function into a maximization function.
-Minimize
$\mathrm{w}=2 \mathrm{y}_{1}+\mathrm{y}_{2}+3 \mathrm{y}_{3}$
Subject to: $3 \mathrm{y}_{1}+2 \mathrm{y}_{2}+\mathrm{y}_{3} \geq 56$
$\mathrm{y} 2+\mathrm{y} 3 \geq 24$
$2 \mathrm{y}_{1}+\mathrm{y}_{2} \geq 30$
$\mathrm{y}_{1} \geq 0, \mathrm{y}_{2} \geq 0, \mathrm{y}_{3} \geq 0$

A) Maximize $z=-y_{2}-y_{3} \leq 24$
B) Maximize $z=-2 y 1-y 2-3 y 3$
C) Maximize $z=2 y 1+y 2+3 y 3-y_{4}$
D) Maximize $z=-2 y_{1}-y_{2} \leq 30$
