2 kuintal = 200 kg
Harga pembelian tiap kg
= 1.280.000 / 200 kg
= Rp 6.400,00
Harga penjualan
= harga pembelian . (1 + %keuntungan)
= 6.400 . (1 + 10%)
= 6.400 . (1 + 0,1)
= 6.400 . 1,1
= Rp 7.040,00
⇒Harga beli :
↬2 kw = 200 kg
↬Rp 1.280.000 / 200
↬Rp 6.400,00 / kg
⇒Harga jual :
↬( 100 + %untung ) / 100 × harga beli
↬( 100 + 10 ) / 100 × 6.400
↬110 / 100 × 6.400
↬110 × 64
↬Rp 7.040,00 [ opsi. C ]
