Misal tabungan awal = A Tabungan akhir = T awal + bunga 3.815.000 = A + Ax12%x9/12 3.815.000 = A + 9%A 3.815.000 = 109/100 A A = 3.815.000 x 100/109 = 3.500.000 (tabungan awal)
109x = 3815000 x 9
109x = 34335000
x =34335000/109
x 315000
tabungn awal = 3815000 - 315000 = 3500000
Tabungan akhir = T awal + bunga
3.815.000 = A + Ax12%x9/12
3.815.000 = A + 9%A
3.815.000 = 109/100 A
A = 3.815.000 x 100/109 = 3.500.000 (tabungan awal)
