A car decreases in value after a given number of years. The following function represents the value of the car in dollars with respect to its age, x, in years: f(x)=35,000(.85)x
. Use the input-output table to determine the value of the car after 5 years. Round your answer to the nearest cent.

(1 point)
Rounded to the nearest cent, after 5 years, the value of the car will equal $
.

Answer 1

To find the value of the car after 5 years using the given function \( f(x) = 35,000(0.85)^x \), we need to substitute \( x = 5 \) into the function.

Let's calculate it step by step:

1. Substitute \( x \) with 5:

\[
f(5) = 35,000(0.85)^5
\]

2. Calculate \( (0.85)^5 \):

\[
(0.85)^5 \approx 0.4437053125
\]

3. Now multiply this by 35,000:

\[
f(5) \approx 35,000 \times 0.4437053125 \approx 15,033.65
\]

Rounded to the nearest cent, after 5 years, the value of the car will equal **$15,033.65**.
