KERTAS SOALAN TAMAT

Gunakan kertas graf untuk menjawab soalan ini.

Sebuah kilang menghasilkan 2 jenis bantal, jenis A dan jenis B. Dalam satu hari, kilang itu

boleh menghasilkan x biji bantal jenis A dan y biji bantal jenis B. Masa yang diambil untuk

menghasilkan sebiji bantal jenis A ialah 20 minit dan sebiji bantal jenis B ialah 30 minit.

Pengeluaran bantal dalam satu hari adalah berdasarkan kekangan yang berikut:

I: Masa yang diambil untuk membuat bantal A tidak melebihi masa yang diambil

untuk membuat bantal jenis B.

II: Jumlah bantal yang dihasilkan tidak melebihi 500 bji.

III: Bilangan bantal jenis B mesti melebihi bilangan bantal jenis A selebih-lebihnya

200 biji.

(a) Tulis tiga ketaksamaan, selain , yang memenuhi semua kekangan di

atas. [3 markah]

(b) Menggunakan skala 2 cm kepada 100 biji bantal pada kedua-dua paksi, bina dan lorek

rantau R yang memenuhi semua kekangan di atas. [3 markah]

(c) Gunakan graf anda daripada 15(b) untuk mencari

(i) bilangan maksimum bantal jenis A jika 280 biji bantal jenis B dihasilkan.

(ii) keuntungan maksimum yang boleh diperolehi, jika keuntungan jualan bagi bantal A

ialah RM20 dan bantal B ialah RM12 00.
