Step 1: Understand the formula for compound interest. The formula is: \( A = P(1 + r)^t \), where \( A \) is the total amount after interest, \( P \) is the principal amount, \( r \) is the annual interest rate (in decimal form), and \( t \) is the time in years.
Step 2: Identify the values given in the problem. Here, \( P = 5000 \), \( r = 0.06 \) (since 6% = 0.06), and \( t = 3 \). Substitute these values into the formula.
Step 3: Calculate the total amount \( A \) after 3 years using the formula \( A = P(1 + r)^t \). This involves first adding \( 1 + r \), then raising the result to the power of \( t \), and finally multiplying by \( P \).
Step 4: Determine the compound interest earned by subtracting the principal \( P \) from the total amount \( A \). The formula for compound interest is \( ext{Interest} = A - P \).
Step 5: Compare the calculated interest to the options provided in the problem to identify the correct answer.
