• A. $2 x + 5 y \geq 80 , x + y \leq 20 , x \geq 0 , y \leq 0$
• B. $2 x + 5 y \geq 80 , x + y \geq 20 , x \geq 0 , y \geq 0$
• C. $2 x + 5 y \leq 80 , x + y \leq 20 , x \geq 0 , y \geq 0$
• D. $2 x + 5 y \leq 80 , x + y \leq 20 , x \leq 0 , y \leq 0$

Answer 1

Answer: (C)

$2 x + 5 y \leq 80 , x + y \leq 20 , x \geq 0 , y \geq 0$

Answer 2
