Uanh yg harus dibayar Ria adalah Rp152.000.
Penjelasan dengan langkah-langkah:
Potongan harga baju
[tex]p= 70.000 \times 20\%[/tex]
[tex]p = 70.000 \times \frac{20}{100} [/tex]
[tex]p = 14.000[/tex]
============================
Harga baju setelah didiskon
= Harga baju - potongan harga
= Rp70.000 - Rp14.000
= Rp56.000
============================
Potongan harga celana
[tex]p = 120.000 \times 25\%[/tex]
[tex]p = 120.000 \times \frac{25}{100} [/tex]
[tex]p =30.000 [/tex]
============================
Harga celana setelah didiskon
= Rp120.000 - Rp30.000
= Rp90.000
============================
Total uang yang harus dibayar Ria
Total = Harga baju + Harga celana
Total = Rp56.000 + Rp90.000
Total = Rp146.000,-
