Answer
After 10 years, the car will be worth approximately $5,557.89.
Solution
To find the value of the car after 10 years, we can use the formula for exponential decay, which is given by:
\[
V = P(1 - r)^t
\]
where:
- \( V \) is the future value of the car,
- \( P \) is the initial value of the car (23700 dollars),
- \( r \) is the rate of depreciation (13.5% or 0.135),
- \( t \) is the time in years (10 years).
Now, let's substitute the known values into the formula:
\[
V = 23700(1 - 0.135)^{10}
\]
First, we need to calculate \( 1 - 0.135 \):
\[
1 - 0.135 = 0.865
\]
Now we can calculate \( 0.865^{10} \):
\[
V = 23700 \times 0.865^{10}
\]
Next, we will calculate \( 0.865^{10} \) and then multiply it by 23700. Let's perform these calculations.
Calculate the value by following steps:
- step0: Calculate:
\(0.865^{10}\)
- step1: Convert the expressions:
\(\left(\frac{173}{200}\right)^{10}\)
- step2: Use the properties of exponents:
\(\frac{173^{10}}{200^{10}}\)
Calculate or simplify the expression \( 23700 * 0.23451 \).
Calculate the value by following steps:
- step0: Calculate:
\(23700\times 0.23451\)
- step1: Multiply the numbers:
\(5557.887\)
Now that we have calculated \( 0.865^{10} \approx 0.23451 \), we can find the future value of the car:
\[
V = 23700 \times 0.23451 \approx 5557.887
\]
Rounding this to the nearest cent, the value of the car after 10 years will be:
\[
\text{Value of the car} \approx 5557.89 \text{ dollars}
\]
Thus, the value of the car after 10 years is approximately **$5557.89**.

To calculate the value of the car after 10 years, we use the formula for depreciation: \[ V = P(1 - r)^t \] Where \( V \) is the future value, \( P = 23700 \) (initial value), \( r = 0.135 \) (depreciation rate), and \( t = 10 \) (time in years). Plugging in the values: \[ V = 23700(1 - 0.135)^{10} \] \[ V = 23700(0.865)^{10} \] Calculating \( (0.865)^{10} \approx 0.2810 \): \[ V \approx 23700 \times 0.2810 \approx 6657.70 \] So, after 10 years, the value of the car will be approximately **$6657.70**.
