Answer:
3 years
Step-by-step explanation:
First year balance = $19,691.28
Monthly payment = $273.49
Annual payment = 273.49×12 = $3281.88
Remaining balance after 1 year = 19,691.28-3281.88
                          = $16,409,4
Continuing in this way,
After 3 years balance = $9845.64
Remaining balance after payment (4 years) = 9845.64-3281.88
                            = $6563.76
Remaining balance after payment (5 years) Â = 6563.76-3281.99
                                     = 3281.88
Remaining balance after payment (6 years) =3281.88-3281.88
                                    = 0
Hence, Inga needs 3 more years to pay off the whole amount.
