3 DISKON PENGERTIAN CONTOH SOAL

4 D D i s k o n / R a b a t D Pengertian “Diskon atau rabat yaitu potongan harga suatu barang yang diberikan penjual kepada pembeli atau konsumen.” P Nilai diskon biasanya diberi dalam bentuk persen ( % ). = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

5 M MASALAH M LATIHAN Di salah satu toko swalayan memberikan potongan harga sebesar 20% untuk setiap pembelian barang yang ada. Nina membeli sebuah kaos seharga Rp ,00. Hitunglah jumlah uang yang dibayarkan Nina. PEMBAHASAN = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

6 P Pembahasan P PEMBAHASAN Diketahui: %diskon = 20%
Harga awal = Rp Ditanyakan: uang dibayar = ? Penyelesaiannya: Untuk menghitung uang yang harus dibayar bisa menggunakan persamaan berikut ini. Uang dibayar = harga awal – harga diskon Uang dibayar = harga awal – Harga awal x % diskon Uang dibayar = Rp – Rp x 20% = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

7 P Pembahasan P PEMBAHASAN
Uang dibayar = Rp – Rp x (20/100) Uang dibayar = Rp – Rp Uang dibayar = Rp Jadi, jumlah uang yang dibayarkan Nina adalah Rp = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

suatu barang dengan kemasannya / tempatnya” Pengertian = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

10 M MASALAH M LATIHAN Ibu membeli 5 kaleng susu. Disetiap kaleng tertulis neto 1 kg. Setelah ditimbang ternyata berat kaleng susu tersebut 6 kg. Berapakah bruto setiap kaleng?. PEMBAHASAN = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

11 P Pembahasan P PEMBAHASAN Diketahui: Banyak kaleng = 5 netto = 1 kg
Berat 5 kaleng = 6 kg Ditanyakan: Bruto setiap kaleng = ? Penyelaiannya: Untuk menghitung bruto setiap kaleng, menggunakan persamaan berikut. Bruto = Berat keseluruhan : banyaknya kaleng Bruto = 6 kg : 5 Bruto = 1,2 kg Jadi, bruto setiap kaleng adalah 1,2 kg = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

12 TARA PENGERTIAN CONTOH SOAL

13 T T a r a T “ Tara adalah berat kemasan / tempat suatu barang”
Pengertian “ Tara adalah berat kemasan / tempat suatu barang” = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

14 M MASALAH M LATIHAN Ibu membeli 5 kaleng susu. Disetiap kaleng tertulis neto 1 kg. Setelah ditimbang ternyata berat kaleng susu tersebut 6 kg. Berapakah tara setiap kaleng? PEMBAHASAN = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

15 P Pembahasan P PEMBAHASAN Diketahui: Banyak kaleng = 5 netto = 1 kg
Berat 5 kaleng = 6 kg Ditanyakan: Tara setiap kaleng = ? Penyelesaiannya: Untuk menghitung tara setiap kaleng, terlebih dahulu mencari bruto untuk setiap kalengnya dengan menggunakan persamaan berikut. Bruto = Berat keseluruhan : banyaknya kaleng Bruto = 6 kg : 5 Bruto = 1,2 kg = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

16 P Pembahasan P PEMBAHASAN
Setelah mengetahui bruto untuk setiap kaleng, langkah selanjutnya menghitung tara menggunakan persamaan berikut. Tara = Bruto - Netto Tara = 1,2 kg - 1 kg Tara = 0,2 kg Jadi, tara setiap kaleng adalah 0,2 kg = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

17 NETTO PENGERTIAN CONTOH SOAL

suatu barang tanpa kemasan / tempatnya” Pengertian = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

19 M MASALAH M LATIHAN Dalam sekantong beras tertulis bruto sebesar 80 kg. Jikan diketahui berat taranya adalah 5 % dari bruto , maka hitunglah nettonya dalam kilogram ? PEMBAHASAN = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

20 P Pembahasan P PEMBAHASAN Diketahui: Bruto = 80 kg Tara = 5% Bruto
Berat 5 kaleng = 6 kg Ditanyakan: Netto sekantong beras dalam kilogram ? Penyelesaiannya: Untuk menghitung netto sekantong beras tersebut , terlebih dahulu mencari tara, dengan menggunukan persamaan berikut. Tara = 5 % bruto ( diketahui) Tara = 5 % X 80 kg Tara = 4 kg = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

21 P Pembahasan P PEMBAHASAN
Setelah tara di ketahui, langkah selanjutnya menghitung netto menggunakan persamaan berikut. Netto = bruto - tara Netto = 80 kg - 4 kg Netto = 76 kg Jadi, netto dari sekantong beras adalah 76 kg = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

22 T TUGAS T TUGAS Sebuah toko elektronik memberikan diskon sebesar 10% untuk semua jenis barang jika dibayar secara tunai.
