You buy a car for $16,000. It will decrease in value by 10% each year. How much will it be worth after 4 years?

Mandarinka [93]

Answer: 9,600

Step-by-step explanation:

I could possibly did wrong but I shall explain this none the less. I first knew that 10% of 16,000 was 1,600. So then I just timed that by four getting 6,400. I then did 16,000-6,400 getting $9,600. Sorry if I’m wrong
