tolong dijawab kk beserta caranya

M○ = Rp 10.500.000,00
p% = 3 1/3 %/bulan
Mt = Rp 307.329.440,00
t = .... bulan???

Mt = M○ + (M○ × p% × t)
Rp 307.329.440,00 = Rp 10.500.000,00 + (Rp 10.500.000,00 × 3 1/3 % × t)
Rp 307.329.440,00 - Rp 10.500.000,00 = Rp
10.500.000,00 × 10/300 × t
Rp 296.829.440,00 = Rp 350.000,00 × t
t = Rp 296.829.440,00/Rp 350.000,00
t = 848,08411 = 848 bulan

Jadi lama Bang Yos menabung selama 848 bulan
