Answer 1

Verified answer

Bunga 1 tahun = 9%
bunga 8 bulan = 8/12 . 9/100
= 72/1200 = 36/600 = 6/100 atau 6%

tabungan awal = x
x + (x . 6/100) = 4505000
x + 6x/100 = 4505000

x + 6x/100
= x/1 + 6x/100
= 100x/100 + 6x/100
= 106x/100

106x/100 = 4505000
106x = 4505000 x 100
106x = 450500000
x = 450500000/106
x = 4.250.000

Tabungan awal = Rp 4.250.000
