Answer: pay more than the minimum payment each month
Step-by-step explanation:
For Elizabeth to responsibly pay off her bill sooner, she has to pay more than the minimum payment each month.
It should be noted that if she continues paying the minimum monthly payment, it'll take her five years and collecting a loan isn't appropriate as well as she will still have to pay back the loan and incur more debt.
Therefore, she should pay more than the minimum amount as that'll make her pay quicker.
