Harga jual = harga beli - rugi harga jual = harga beli - (10% x harga beli) harga jual = 90% x harga beli 18.000 = 90/100 x harga beli harga beli = 18.000 : 90/100 harga beli = 18.000 x 100/90 harga beli = 20.000
agar untung 9% harga jual = harga beli + untung harga jual = harga beli + (9% x harga beli) harga jual = 20.000 + (9% x 20.000) harga jual = 20.000 + 1.800 harga jual = 21.800
Verified answer
Harga jual = harga beli - rugiharga jual = harga beli - (10% x harga beli)
harga jual = 90% x harga beli
18.000 = 90/100 x harga beli
harga beli = 18.000 : 90/100
harga beli = 18.000 x 100/90
harga beli = 20.000
agar untung 9%
harga jual = harga beli + untung
harga jual = harga beli + (9% x harga beli)
harga jual = 20.000 + (9% x 20.000)
harga jual = 20.000 + 1.800
harga jual = 21.800
