Minimize $c = 2.2 x + y + 3.3 z$
Subject to
$$\begin{aligned}x + 1.5 y + 1.2 z & \geq 150 \\2 x + 1.5 y & \geq 40 \\1.5 y + 1.1 z & \geq 40 \\x \geq 0 , y \geq 0 , z & \geq 0\end{aligned}$$
Round all answers to two decimal places.

A) $c = 320$ , $x = 100$ , $y = 100$ , $z = 0$
B) $c = 330$ , $x = 0$ , $y = 0$ , $z = 100$
C) $c = 100$ , $x = 0$ , $y = 100$ , $z = 0$
D) $c = 550$ , $x = 100$ , $y = 0$ , $z = 100$
E) $c = 220$ , $x = 100$ , $y = 0$ , $z = 0$
