Step 1: Understand the formula for compound interest, which is \( A = P \cdot (1 + r)^t \), where \( A \) is the future value of the investment, \( P \) is the principal amount, \( r \) is the annual interest rate (in decimal form), and \( t \) is the number of years the investment is held.
Step 2: Identify the values given in the problem: \( P = 1000 \), \( r = 0.05 \) (convert \( 5\% \) to decimal), and \( t = 3 \).
Step 3: Substitute the values into the formula: \( A = 1000 \cdot (1 + 0.05)^3 \).
Step 4: Simplify the expression inside the parentheses: \( 1 + 0.05 = 1.05 \), so the formula becomes \( A = 1000 \cdot (1.05)^3 \).
Step 5: Calculate \( (1.05)^3 \) and then multiply the result by \( 1000 \) to find the future value of the investment. This will give the final answer.
