Daging = 4gr & 2gr
10kg ≤ 4gr & 2gr
10000 ≤ 4x + 2y (disederhanakan ÷2)
2x + y ≤ 5000
Tepung Sagu = 10gr & 6gr
20kg ≤ 10gr + 6gr
20000 ≤ 10x + 6y (disederhanakan ÷2)
5x + 3y ≤ 10000
Jadi, model matematikanya: 2x + y ≤ 5000, 5x + 3y ≤ 10000, x ≥ 0, y ≥ 0

Ragi = 3gr & 6gr
6kg ≤ 3gr + 6gr
6000 ≤ 3x + 6y (disederhanakan ÷3)
x + 2y ≤ 2000
Kedelai = 6ons & 8ons
12kwintal ≤ 6ons + 8ons
12000 ≤ 6x + 8y (disederhanakan ÷2)
3x + 4y ≤ 6000
Jadi, model matematikanya: x + 2y ≤ 2000, 3x + 4y ≤ 6000, x ≥ 0, y ≥ 0
