	A	B	C	D
Food I:	2	1	1	2
Food II :	1	1	2	3

Assuming x kgs of food I is to be mixed with y kgs of food II the situation can be expressed as:

2x + y ≤ 9
x + y ≤ 7
x +2 y ≤ 10
2x +3 y ≤ 12
x > 0, y > 0
2x + y ≥ 30
x + y ≤ 7
x + 2y ≥ 10
x + 3y ≥ 12
x ≥ 0; y ≥ 0.
2x + y ≥ 9
x + y ≤ 7
x + 2y ≤ 10
x + 3y ≥ 12
x ≥0, y ≥ 0
2x + y ≥ 9
x + y ≥ 7
x + 2y ≥ 10
2x + 3y ≥ 12
