Question

Qual o capital que aplicado a juros compostos produz 2.050,00 de juros, em dois meses a 5% a.m?

Answer 1

M=c(1+i)^t
2050=c(1+0,05)²
2050=c(1,05)²
2050=c(1,1025
capital(c)=2050/1,1025
c=1 8 60

Answer 2

M = 2050 + C
t = 2m
i = 5% a m = 5/100 = 0,05

2050 + C =  C ( 1 + 0,05)²
2050 + C = C * 1,05² 
2050 + C  = 1,1025C
2050  = 1,1025C - 1C 
2050 = 0,1025C
C = 2050/0,1025
C =20 000 ***
