Explicação passo-a-passo:

$12)J=c.i.t\\83,25=370,00.0,025.t\\t=\frac{83,25}{9,25}\\t=9\ meses\\\\13.a)J=c.i.t\\J=1600,00.(\frac{30\%}{12}).3\\J=1600,00.0,025.3\\J=120,00\\b)M=C+J\\M=1600,00+120,00\\M=1720,00\\\\14)J_{simples}=c.i.t\\J_{simples}=400000,00.0,04.3\\J_{simples}=48000,00\\M=C.(1+i)^t\\M=400000,00.(1+0,04)^3\\M=449945,60\\J_{compostos}=M-C\\J_{compostos}=449945,60-400000,00\\J_{compostos}=49945,60\\\\15)M=C.(1+i)^t\\M=8000,00.(1+0,025)^2\\M=8405,00$
