Tolong jawab nomer 7 sama 8 ya pake cara ya

7. harga beli 20 kg = Rp 120.000,00
harga jual 1 kg = 6.500

6500 x 20 = 130.000

130.000 – 120.000 = Rp 10.000 → keuntungan yg didapat

8. 240.000 x 20% = 48.000 → keuntungan yg didapat.

240.000 – 48.000 = Rp 192.000,00 → harga beli

7. untung:
= 6.500×20 – 120.000
= 130.000 – 120.000
= 10.000

8. harga beli:
= 100%/100%+20% x 240.000
= 100%/120% x 240.000
= 200.000
