Question 1106187
.
<pre>
Let X = kilos of pork, Y = kilos of beef.


Inequalities  (= mathematical model)

    x + Y >= 30,

    180X + 220Y <= 1200

    x >= 0,  Y >= y.


The plots are below:


{{{graph( 330, 330, -2.5, 40.5, -2.5, 40.5,
          30-x,  (1200-180x)/220
)}}}


Plots  X + Y = 30 (red),  180X + 220Y = 1200 (green).



The solution domain is the area in QI over the red line and below green line.


It is the EMPTY set (empty intersection). Which means that the problem  <U>HAS NO</U>  solutions.


The set of solutions to the given problem is  <U>EMPTY</U>.
