Final answer:
An individual must be at least 18 years old to get a credit card on their own, and should be aware of interest rates and debt responsibilities that come along with the use of credit cards.
Therefore, the correct answer is: option 2) 18
Step-by-step explanation:
You must be at least 18 years old to get a credit card on your own in the United States.
However, there are some exceptions for minors who can obtain a credit card if they are an authorized user on an adult's account or if they can prove independent income to pay off the debt incurred on the card.
It is important to be aware of the responsibilities that come with using a credit card, as they allow you to borrow money from the card's issuer.
You are expected to pay back the borrowed amount plus interest. Interest rates on credit cards typically range between 12% to 18% per annum.
High levels of credit card debt, such as the $807 billion outstanding in May 2021, can lead to extensive amounts paid in interest, as well as fees for the credit card or for late payments.
