To find out how much Allison will owe in 3 years, we use the formula for compound interest: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] Where: - \( A \) is the amount owed after time \( t \), - \( P \) is the principal amount (initial debt), - \( r \) is the annual interest rate (as a decimal), - \( n \) is the number of times the interest is compounded per year, and - \( t \) is the number of years. Plugging in the values: - \( P = 7000 \), - \( r = 0.15 \), - \( n = 4 \) (quarterly compounding), - \( t = 3 \). The calculation would be: \[ A = 7000 \left(1 + \frac{0.15}{4}\right)^{4 \times 3} \] \[ A = 7000 \left(1 + 0.0375\right)^{12} \] \[ A = 7000 \left(1.0375\right)^{12} \] Now, calculating \( (1.0375)^{12} \): \[ (1.0375)^{12} \approx 1.491825 \] Thus: \[ A \approx 7000 \times 1.491825 \approx 10443.78 \] Therefore, after 3 years, Allison will owe approximately **$10,443.78** on her credit card debt.
