2.    Disebuah rental computer menerima jasa print dengan tariff print HP = Rp.500,-/lbr, Print BW Rp. 1000,-/lbr danjika dalam rental tersebut memberikan discount 10% untuk print per 10lbr. Maka berapakah total biaya yang akan kita bayar setiap kita melakukan print di rental tersebut ? buat flowchart dan program dengan inputan keyboard !

OPI

Output :  total biaya harga print

               Dengan ketentuan :

               Hp (Hitam putih) = Rp.500,-/lbr

               Bwn (Berwarna)  = Rp.1000,-/lbr

               Discount 10% untuk print per 10 lembar untuk masing masing jenis print

Proses :   -menentukan harga diskon untuk setiap jenis print

1.      Harga diskon print Hp (10 x 500) x 90% = 4500

2.      Harga diskon print Bwn (10 x 1000) x 90 % = 9000

-menentukan banyaknya print yang mendapat diskon

1. sisa print Hp = N print Hp % 10 

2. jumlah diskon print Hp = (N print Hp – sisa print Hp) /10

Untuk berwarna.

1.      Sisa print Bwn = N print Bwn  % 10

2.      Jumlah diskon print Bwn = (N print Bwn – sisa print Bwn)/10.

-menentukan harga yang harus dibayar

1.      print Hp :

         Total diskon Hp = jumlah diskon x harga diskon

         Harga sisa print Hp = sisa print Hp x harga per lembar

         Total harga Hp = Total diskon Hp + Harga sisa print Hp

2              print Bwn :

Total diskon Bwn = jumlah diskon x harga diskon

Harga sisa print Bwn = sisa print Hp x harga per lembar

Total harga Bwn = Total diskon Bwn x Harga sisa print Bwn

               -harga yang harus dibayar :

               Total harga = Total harga Hp + Total harga Bwn

Input :    N hp

               N Bwn

 

Flowchart

Analisa

Input :       print Hp = 24

                    Print Bwn = 15

Proses :    Harga diskon print Hp (10 x 500) x 90% = 4500

Harga diskon print Bwn (10 x 1000) x 90 % = 9000

               Sisa print Hp =  print Hp  % 10

               4 = 24%10

               Jumlah diskon print Hp = (N print Hp – sisa print Hp)/10

               Jumlah diskon print = (24 – 4) / 10

               2 = 20 / 10

               Sisa print Bwn = N print Bwn  % 10

               5 = 15 % 10

               Jumlah diskon print Bwn = (N print Bwn – sisa print Bwn)/10

               Jumlah diskon print Bwn = ( 15 – 5) / 10

               1 = 10 / 10

print Hp :

         Total diskon Hp = jumlah diskon x harga diskon

         9000 = 2 x 4500

         Harga sisa print Hp = sisa print Hp x harga per lembar

         2000 = 4 x 500

         Total harga Hp = Total diskon Hp + Harga sisa print Hp

         11000 = 9000 + 2000

               print Bwn :

Total diskon Bwn = jumlah diskon x harga diskon

9000 = 1 x 9000

Harga sisa print Bwn = sisa print Hp x harga per lembar

5000 = 5 x 5000

Total harga Bwn = Total diskon Bwn x Harga sisa print Bwn

14000 = 9000 + 5000

               Total harga = Total harga Hp + Total harga Bwn

               25000 = 11000 + 14000
