gimana ini plis jwb y

harga awal
8 kw = 800kg
1 kw = Rp 500.000,00 => 1

kg = 500.000:100 = 5000/kg
harga = 800×5000= 4.000.000

harga jual = 6000×800= 4.800.000

presentase
[tex] \frac{4800000 - 4000000}{4800000} \times 100\%
= \frac{800000}{4800000} \times 100\%
= \frac{1}{6} \times 100\%
= 16.6\% [/tex]
