A new car is purchased for 15100 dollars. The value of the car depreciates at 13% per year. To the nearest tenth of a year, how long will it be until the value of the car is 1900 dollars?

The price of car will be $1,900 after 14.9 years.

Step-by-step explanation:

Formula of depreciate:

A= The price of the car after n years.

P= The initial price of the car

r= rate of depreciate

n=time in years.

Given that,

A new car is purchased for $ 15,100.

The value of car depreciates at 13% per year.

Here P=$15,100, A=$1,900, r=13%=0.13, n=?

Tanking ln function both sides

⇒n ≈14.9

The price of car will be $1,900 after 14.9 years.
