Compare the investment below to an investment of the same principal at the same rate compounded annually. principal: \( \$ 2,000 \), annual interest: \( 9 \% \), interest periods: 12 , number of years: 10 After 10 years, the investment compounded periodically will be worth \( \$ \square \) more than the investment compounded annually. (Round to two decimal places as needed.)

Beyond the Answer
Let's first calculate the future value of the investment compounded annually. The formula for calculating future value (FV) when compounded annually is: \[ FV = P(1 + r)^n \] Where: - \( P \) is the principal amount (\$2000), - \( r \) is the annual interest rate (9% or 0.09), - \( n \) is the number of years (10). So for compounding annually, we have: \[ FV = 2000(1 + 0.09)^{10} = 2000(1.09)^{10} \approx 2000 \times 2.36736 \approx 4734.73 \] Now, let's calculate the future value of the investment compounded periodically. The formula for future value when compounded periodically with \( m \) times a year is: \[ FV = P\left(1 + \frac{r}{m}\right)^{mt} \] In this case, the investment is compounded 12 times a year (monthly), so \( m = 12 \): \[ FV = 2000\left(1 + \frac{0.09}{12}\right)^{12 \times 10} = 2000\left(1 + 0.0075\right)^{120} \] \[ = 2000(1.0075)^{120} \approx 2000 \times 2.45774 \approx 4915.48 \] Now, we calculate how much more the investment compounded periodically is worth compared to the investment compounded annually: \[ 4915.48 - 4734.73 \approx 180.75 \] Thus, after 10 years, the investment compounded periodically will be worth approximately \( \$180.75 \) more than the investment compounded annually.
