Question

qual o montante de uma capital de R$5.742,00 aplicado a juros simples de 2,34% am durante 2 anos

Answer 1

$\begin{cases}C=5.742\\ i=2,34\%~a.m.=2,34/100=0,0234\\ t=2~anos=24~meses\\ M=C[1+(it)] \end{cases}$

$M=5.742\cdot[1+(0,0234\cdot24)]\\ M=5.742\cdot(1+0,5616)\\ M=5.742\cdot1,5616\\\\ \Large\boxed{M\approx8.966,7072~~ou~~M=8.966,71}$
