Tolong jawab dan pakai cara ya

harga beli = 392.000
PPN = 12%
harga ecer = ?

harga ecer = 100%
harga beli = harga ecer + PPN = 100 + 12 = 112%

harga ecer
= 100/112 × 392.000
= 25/28 × 392.000
= 350.000

semoga membantu ^^

[tex] \frac{12}{100} \times 392000 = 47040 \\ 392000 - 47040 = 344960[/tex]
