Пошаговое объяснение:
Формула простого процента общая для всех случаев S=S₀*(1+rn/100)
1) S=3840, S₀=3000, n=2, r=?
3840=3000*(1+(r*2/100)
3000+60r=3840
60r=840
r=840:60
r=14% годовых
2) S = 4000, r=25%. n=4, S₀=?
4000=S₀*(1+25*4/100)
S₀*(1+1)=4000
S₀=4000:2
S₀=2000 манат первоначальная сумма вклада
3) S₀=5000, S=7295, r=15,3%, n=?
7295=5000*(1+15,3*n/100)
5000+50*15,3n=7295
765n=2295
n=2295:765
n=3 года срок вклада
4) S₀=7000, r=11,5%, n=10 лет , S=?
S= 7000*(1+11,5*10/100)=7000+70*11,5=7000+8050=15050 манат , конечная сумма
