Question

qual capital que aplica a juros simoles de 2% a.m. Rende 3.500,00 de juros em 75 dias

Answer 1

3500=C×2/100×75/30
$350000 = c \times 2 \times \frac{75}{30}$
simplificando 75/30 por 15 =5/2
$350000 = c \times \frac{10}{2} \\ 350000 = 5c \\ c = 70000$

Answer 2

C=j*100/i/t

C=3500*100/2/75*30

C=350000/2/75*30

C=175000/75*30

C=2333,33...*30

C=70000

Resposta: Capital de R$70.000,00
