Respuesta :
Let
x--------> the number of gray bricks
y--------> the number of red bricks
we know that
[tex]y < \frac{x}{2}[/tex] ------> inequality 1
[tex]0.45x+0.58y \leq 200[/tex] -----> inequality 2
therefore
the answer is
x > 0
0.45x+0.58y≤200
Answer:
0.45x + 0.58y ≤ 200
x > 0
0 < y < [tex]\frac{1}{2}[/tex] x
