Final answer:
It will take Joe around 8.3 years to pay off his Citi credit card debt by making monthly minimum payments of $29.
Step-by-step explanation:
Joe's first credit card, Citi, has a balance of $1,900. Since he is making monthly minimum payments of $29, it will take him several months to pay off the debt. The minimum payment is a fixed amount, so it will not decrease as the balance decreases. With an APR of 14.4%, including principal and interest, it would take Joe around 99.25 months (approximately 8.3 years) to pay off the Citi credit card debt.
