Convert the Objective Function into a Maximization Function $w=y_{1}+y_{2}+5 y_{3}$ Subject To

Multiple Choice

Convert the objective function into a maximization function.
-Minimize $w=y_{1}+y_{2}+5 y_{3}$
Subject to: $\mathrm{y}_{1}+\mathrm{y}_{3} \geq 28$
$\mathrm{y}_{1}+2 \mathrm{y}_{2}+3 \mathrm{y}_{3} \geq 59$
$2 \mathrm{y}_{1}+3 \mathrm{y}_{2}+2 \mathrm{y}_{3} \geq 85$
$\mathrm{y}_{1} \geq 0, \mathrm{y}_{2} \geq 0, \mathrm{y}_{3} \geq 0$

A) Maximize $z=-y_{1}-y_{2}-5 y_{3}$
B) Maximize $z=-y_{1}-y_{3} \leq 28$
C) Maximize $z=y_{1}+y_{2}+5 y_{3}-y_{4}$
D) Maximize $z=y_{1}-2 y_{2}-3 y_{3} \leq 59$
