Gabarito Letra C

(4000/1,12) + (4000/1,12^2) + (4000/1,12^3) + (3000/1,12^4) + (3000/1,12^5) + (3000/1,12^6) + (1000/1,12^7) + (1000/1,12^8) + (1000/1,12^9) + (1000/1,12^10) = 16.275

ou

A = (4000 x A3¬12) + 3000 x A3¬12 + 1000 x A4¬12
                                  (1+0,12)^3          (1+0,12)^6

A = (4000 x 2,401831) + 3000 x 2,401831 + 1000 x 3,037349
                                      1,404928                  1,973822

A = 9.607,32 + 5.128,73 + 1.538,82
A = 16.274,87
