Answer 1

Resposta:

Explicação passo-a-passo:

1)

C = 3000

n = 8 meses

i = 3% AM

J = ?

J = c.i.n

J = 3000.3/100.8

J = 30.3.8

J = 90.8

J = 720

R.: R$ 720,00

----------------------

2)

C = 18000

n = 6 meses

i = 4% a.m

J = ?

J = c.i.n

J = 18000.4/100.6

J = 180.4.6

J = 720.6

J = 72.10.6

J = 4320

R.: R$ 4320,00

_____________

3)

J = ?

C = 2500

n = 7 meses

i = 5% am

J = c.i.n

J = 2500.5/100.7

J = 25.5.7

J = 125.7

J = 875

R.: R$ 875,00

________________

4)

C = 8000

n = 5 meses

i = 4% a.m

J = ?

J = c.i.n

J = 8000.4/100.5

J = 80.4.5

J = 80.20

J = 1600

R.: R$ 1600,00

________

5)

J = ?

C = 500000

n = 9

J =

i = 3% a.m.

J = c.i.n

J = 500000.3/100.9

J = 5000.3.9

J = 15000.9

J = 15.9.1000

J = 135000

R.: R$ 135000,00
