Question

alguém me ajuda com cálculos de juros simples??

Answer 1

Sexta-20,000,00×1,2×18/100=432,000,00/100=4,320,00
B)-
5,600,00×12×4/100=268,800,00/100=2,688
C)-680,00×1.9×24/100=31,008/100=
310.08
Sétima-65,70=1,500,00×0,5×T/100->
65,70=750t/100->65,70=7,5t->t=8,76
Oitava-21,657,00-15,624,00=6,033

Answer 2

j=c*i*t

6.
a)20.000×0,012.18 =4.320,00
b)0,12 ao ano em 48 meses= 48÷12= 4
5600*0,12*4= 2.688,00
c)2 anos = 24 meses
680*0,019×24= 310,08

7.
67,50=1500*0,005*t
67,50=7,5t
67,50/7,5=t
tempo = 9 meses
8.
m=c.(1+(i.n))
21.675,00=15.624,00(1+in)
21.675=15624in
21.675/15.624=in
1.38
sera a taxa de juros ao tempo
