A new car worth $24,000 is depreciating in value by $3,000 per year. After how many years will the car’s value be 9,000?

Let's assume that the car's value after 'n' years is $9,000.

Since the car is depreciating by $3,000 per year, we can set up the equation:
$24,000 - $3,000n = $9,000
Now we solve for 'n':
$3,000n = $24,000 - $9,000
$3,000n = $15,000
n = $15,000 / $3,000
n = 5
After 5 years, the car's value will be $9,000.
