.
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:





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  HAS NO  solutions.


The set of solutions to the given problem is  EMPTY.
