Question

A new car is purchased for 21300 dollars. The value of the car depreciates at 5.75%

per year. To the nearest tenth of a year, how long will it be until the value of the car is
9200 dollars?
Answer: 14.2

Answer 1

14.2

Explanation:

You make the equation: y = 21300 (0.9425)^t

Now the y value should be 9200 so you set that equal to y. 9200/21300= 0.9425^t

t=14.2 years

Hope this helps!
