Tolong yg bisa nomer 31-33 gimn yaa caranya??Tolong yaa bsk di kumpulin:(

31. 80/100x90.000=72.000 B
32. 102.5/100x650.000=66250 C
33. 102.5/100x18000000= 18450000 C

31. 20% = 20/100
20/100 × 90.000 = 18.000
Jd, yg harus dibayar = 90.000-18.000 = Rp. 72.000 (B)
32. 2,5% = 25/10/100 = 25/10 : 100 = 25/10 × 1/100 = 25/1000
25/1000 × 650.000 = 16.250
Jd, uang pembayaran & pajak = 650.000+16.250 = Rp.666.250 (C)
33. 2,5% = 25/10/100 = 25/10 : 100 = 25/10 × 1/100 = 25/1000
25/1000 × 18.000.000 = 450.000
Jd, uang motor + pajak = 18.000.000 + 450.000 = Rp.18.450.000 (C)
