Transcript text: Time Value Money
\[
V_{E}=V_{B}(1+r)^{n}
\]
Where
$V_{E}$ : ending value
$\mathrm{V}_{\mathrm{B}}$ : beginning value
$r$ : interest rate usually quoted as annual percentage rate (APR)
n : number of compounding periods
You invest \$2000 into a savings account that earns 2\% APR. How much is your \$2000 worth after 15 years? Include units and round your answer to the nearest dollar (the nearest unit).
Answer: O\$ $\square$
Solution
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 \(\boxed{2692}\).
