To find the future value of an account with compound interest, you can use the formula: \[ A = P(1 + r)^n \] where: - \( A \) is the amount of money accumulated after n years, including interest. - \( P \) is the principal amount (the initial deposit). - \( r \) is the annual interest rate (decimal). - \( n \) is the number of years the money is invested or borrowed. In this case: - \( P = 5500 \) - \( r = 0.025 \) (which is 2.5% as a decimal) - \( n = 10 \) Plugging the numbers into the formula: \[ A = 5500(1 + 0.025)^{10} \] Calculating it step-by-step: 1. Calculate \( 1 + 0.025 = 1.025 \). 2. Raise this to the power of 10: \( 1.025^{10} \approx 1.2800845 \). 3. Multiply by the principal: \[ A \approx 5500 \times 1.2800845 \approx 7040.46475 \] Rounding to the nearest cent, the account will be worth approximately \( \$ 7,040.46 \) in 10 years.
