Solution Steps

To solve this problem, we will use the formula for compound interest to calculate the ending value of an investment. We have the beginning value (\$2000), the annual interest rate (2% or 0.02 as a decimal), and the number of compounding periods (15 years). We will plug these values into the formula to find the ending value.

Step 1: Identify the Variables

We are given the following values:

  • \( V_B = 2000 \) (beginning value in dollars)
  • \( r = 0.02 \) (annual interest rate as a decimal)
  • \( n = 15 \) (number of compounding periods in years)
Step 2: Apply the Compound Interest Formula

We will use the formula for compound interest: \[ V_E = V_B(1 + r)^n \] Substituting the known values into the formula: \[ V_E = 2000(1 + 0.02)^{15} \]

Step 3: Calculate the Ending Value

Calculating the expression: \[ V_E = 2000(1.02)^{15} \approx 2000 \times 1.349353 \approx 2691.7366766482596 \] Rounding this value to the nearest dollar gives: \[ V_E \approx 2692 \]

Final Answer

The value of the investment after 15 years is \(\boxed{2692}\).
