Answer 1

Resposta:

Vamos lá!

a) C = 6780  I = 3%  T = 6 meses

$m=c+(cit)\\\\m=6780+(6780.(0,03).6\\\\m=6780+1220,4\\\\m=8000,40_{reais}$

b) C = 5880  I = 4%  T = 5 meses

$m=c+(cit)\\\\m=5880+(5880.(0,04).5\\\\m=5880+1176\\\\m=7.056,00_{reais}$

c) C = 7780  I = 6%  T = 8 meses

$m=c+(cit)\\\\m=7780+(7780.(0,06).8\\\\m=7780+3734,4\\\\m=11.514,40_{reais}$

d) C = 9280  I = 2%  T = 5 meses

$m=c+(cit)\\\\m=9280+(9280.(0,02).5\\\\m=9280+928\\\\m=10.208,00_{reais}$

e) C = 4780  I = 7%  T = 9 meses

$m=c+(cit)\\\\m=4780+(4780.(0,07).9\\\\m=4780+3011,4\\\\m=7.791,40_{reais}$
