Question

ola por jentileza da para Resolver essas contas pra mim fazendo favor

Answer 1

1-
M=C*(1+i)^t

M=12500*(1,03)³

M=12500*1,092727

M=13659,08 Reais

J=M-C

J=13659,08-12500

J=1159,08 Reais

-------------------------------------------
2-
^ significa elevado a

M=13700*(1,13)^7

M=13700*(2,352...)

M=32230,70 Reais

J=32230,7-13700

J=18530,70

------------------------
3-
1 ano=12 meses

M=26600*(1,03)^12

M=26600*(1,42576...)

M=37925,24 Reais

J=37925,24-26600

J=11325,24

-------------

PS:   * significa multiplicação
