Question

calcular a juros simples de r$1.200,00 a 13%a.t por 4meses e 15 dias

Answer 1

j=C*i/100*t

j=1200*13/100/90*135
j=15600/100/90*135
j=156/90*135
j=1,733*135
j=234
Resposta: Juros de R$234,00

Answer 2

c= 1.200,00
i= 13% a.t. = 13/100 = 0,13
t= t= 4 meses e 15 dias = 4,5(meses) / 3(trimestre) = 1,5

j=cit
j=1.200*0,13*1,5
j= 1.200*0.195
j=234

R= R$234,00
