Explicação passo-a-passo:

1)

C = 3000 t = 7 j = 630

j = C.i.t/100

630 = 3000 . i . 7/100

630 = 21000i/100

630 . 100 = 21000i

63000 = 21000i

63000/21000 = i

i = 3%

2)

C = 2300 t = 2 j = 230

j = C.i.t/100

230 = 2300 . i . 2/100

230 = 4600i/100

230 . 100 = 4600i

23000 = 4600i

23000/4600 = i

i = 5%

3)

C = 2000 t = 9 j = 720

j = C.i.t/100

720 = 2000 . i . 9/100

720 = 18000i/100

720 . 100 = 18000i

72000 = 18000i

72000/18000 = i

i = 4%

4)

C = 4200 t = 10 j = 2100

j = C.i.t/100

2100 = 4200 . i . 10/100

2100 = 42000i/100

2100 . 100 = 42000i

210000 = 42000i

210000/42000 = i

i = 5%

5)

C = 4100 t = 21 j = 2583

j = C.i.t/100

2583 = 4100 . i . 21/100

2583 = 86100i/100

2583 . 100 = 86100i

258300 = 86100i

258300/86100 = i

i = 3%

6)

C = 1200 t = 8 j = 192

j = C.i.t/100

192 = 1200 . i . 8/100

192 = 9600i/100

192 . 100 = 9600i

19200 = 9600i

19200/9600 = i

i = 2%

7)

C = 2200 t = 20 j = 880

j = C.i.t/100

880 = 2200 . i . 20/100

880 = 44000i/100

880 . 100 = 44000i

88000 = 44000i

88000/44000 = i

i = 2%

8)

C = 1300 t = 13 j = 338

j = C.i.t/100

338 = 1300 . i . 13/100

338 = 16900i/100

338 . 100 = 16900i

33800 = 16900i

33800/16900 = i

i = 2%

9)

C = 1000 t = 22 j = 660

j = C.i.t/100

660 = 1000 . i . 22/100

660 = 22000i/100

660 . 100 = 22000i

66000 = 22000i

66000/22000 = i

i = 3%

10)

C = 3200 t = 6 j = 960

j = C.i.t/100

960 = 3200 . i . 6/100

960 = 19200i/100

960 . 100 = 19200i

96000 = 19200i

96000/19200 = i

i = 5%
