Ali, Badar, dan Carli berbelanja di sebuah toko buku. Ali membeli dua buah buku tulis, sebuah pensil, dan sebuah penghapus. Ali harus membayar Rp 4.700,00. Badar membeli sebuah buku tulis, dua buah pensil, dan sebuah penghapus dan Badar harus membayar Rp 4.300,00 . Carli membeli tiga buah buku tulis, dua buah pensil, dan sebuah penghapus Carli harus membayar Rp7.100,00.
Jika dimisalkan Ali = x, Badar = y dan Carli = z, maka model matematika yang tepat untuk pernyataan di atas adalah . . . . . . .
2x + y + z = 4.700
x + 2y + z = 4. 300
3x + 2y + z = 7. 100
2x + y + z = 4.700
2y - x + z = 4. 300
3x + 2y + z = 7. 100
2x + y + z = 4.700
x + 2y + z = 4. 300
2y + 3z + 2z = 7. 100
2x + y + z = 4.700
x + 2y - z = 4. 300
3x - 2y + z = 7. 100

Sebuah kios menjual bermacam-macam buah di antaranya jeruk, salak, dan apel. Seseorang yang membeli 1 kg jeruk, 3 kg salak, dan 2 kg apel harus membayar Rp33.000,00. Orang yang membeli 2 kg jeruk, 1 kg salak, dan 1 kg apel harus membayar Rp23.500,00. Orang yang membeli 1 kg jeruk, 2 kg salak, dan 3 kg apel harus membayar Rp36.500,00.
Jika 1 kg jeruk = x, 1 kg salak = y dan 1 kg apel = z, dari pernyataan di atas maka dapat dibuat model matematikanya . . . . . .
x + 3y + 2z = 33.000
2x + y + z = 23.500
3x + 2y + 3z = 36. 500
x + 3y + 2z = 33.000
2x + y + z = 23.500
x + 2y + 3z = 36. 500
x + 3y + 2z = 33.000
2x + y + z = 36. 500
x + 2y + 3z = 23. 500
x + 3y + 2z = 33.000
2x + y + z = 23.500
2y+ 3x + 3z = 36. 500
