2x + y + z = 76.000
x + 2y + 3z = 108.000
2x + 3y + z = 146.000
2x + 2y + z = 76.000
x + 2y + 3z = 108.000
2x + 3y + 3z = 146.000
x + y + z = 76.000
x + 2y + 3z = 108.000
2x + 3y + 3z = 146.000
2x + 2y + z = 76.000
x + 2y + 2z = 108.000
2x + 3y + 3z = 146.000

Harga 1 kg beras Rp. 12.000,- dan 1 kg gula Rp. 16.000. Seorang pedagang memiliki modal Rp. 1.600.000,-. Dan tempat yang tersedia hanya memuat 1 kuintal. Jika pedagang tersebut membeli x kg beras dan y kg gula, maka model matematika dari sistem pertidaksamaan di atas adalah.......
12.000x + 16.000y ≤ 1.600.000 ;
x + y ≤ 100 ;
x ≥ 0 ; y ≥ 0
12.000x + 16.000y = 1.600.000 ;
x + y = 100 ;
x ≥ 0 ; y ≥ 0
12.000x + 16.000y ≥ 1.600.000 ;
x + y ≥ 100 ;
x ≥ 0 ; y ≥ 0
12.000x + 16.000y < 1.600.000 ;
x + y < 100 ;
x ≥ 0 ; y ≥ 0
