Solution
Solution Steps
Step 1: Convert the annual interest rate from a percentage to a decimal
To convert the annual interest rate to a decimal, we divide the rate by 100. Thus, \(r = 0.5 / 100 = 0.0.5\).
Step 2: Use the compound interest formula to calculate the future value \(A\)
The formula to calculate the future value \(A\) is given by \(A = P(1 + \frac{r}{n})^{nt}\), where \(P = 6000\), \(r = 0.0.5\), \(n = 4\), and \(t = 5\).
Substituting the values, we get \(A = 6000 \times (1 + \frac{0.0.5}{4})^{4 \times 5} = 6151.79\).
Step 3: Calculate the interest earned
The interest earned over the period is the future value minus the principal, which is \(A - P = 6151.79 - 6000 = 151.79\).
Final Answer:
The future value of the investment after 5 years is $6151.79, and the interest earned over this period is $151.79.
