To find the balance \( A \) in the account after 5 years with quarterly compounding, we can use the formula: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] where: - \( P \) is the principal amount (initial investment) = \( 250,000 \) - \( r \) is the annual interest rate (as a decimal) = \( 0.03 \) - \( n \) is the number of times that interest is compounded per year = \( 4 \) - \( t \) is the number of years the money is invested = \( 5 \) Plugging in the values: \[ A = 250,000 \left(1 + \frac{0.03}{4}\right)^{4 \times 5} \] \[ A = 250,000 \left(1 + 0.0075\right)^{20} \] \[ A = 250,000 \left(1.0075\right)^{20} \] Now calculating \( (1.0075)^{20} \): \[ (1.0075)^{20} \approx 1.1616 \] Finally, we calculate \( A \): \[ A \approx 250,000 \times 1.1616 \approx 290,404 \] Therefore, the balance in the account after 5 years is approximately \( \$290,404 \).
