A new car worth \( \$ 30,000 \) is depreciating in value by \( \$ 3,000 \) per year. After how many years will the car's value be \( \$ 6,000 \) ? After \( \square \) years, the car's value will be \( \$ 6,000 \).

Step-by-step Solution
To find out after how many years the car's value will be \( \$ 6,000 \), we can set up the following equation based on the information given:
1. The initial value of the car is \( \$ 30,000 \).
2. The car depreciates by \( \$ 3,000 \) per year.
3. We want to find the number of years \( x \) when the car's value will be \( \$ 6,000 \).
The value of the car after \( x \) years can be expressed as:
\[
\text{Value after } x \text{ years} = 30,000 - 3,000x
\]
We want this value to equal \( 6,000 \):
\[
30,000 - 3,000x = 6,000
\]
Now, we can solve for \( x \):
1. Subtract \( 30,000 \) from both sides:
\[
-3,000x = 6,000 - 30,000
\]
\[
-3,000x = -24,000
\]
2. Divide both sides by \( -3,000 \):
\[
x = \frac{-24,000}{-3,000} = 8
\]
Thus, after \( 8 \) years, the car's value will be \( \$ 6,000 \).
So, the answer is:
After \( \boxed{8} \) years, the car's value will be \( \$ 6,000 \).
Quick Answer
After 8 years, the car's value will be $6,000.
