Value of a new car depreciates at a rate of 12% per year.

Approximately how many years will it take until the car is worth $2300?

What is the cost of the new car?

$23000, forgot.

i will repost

original value = 23,000

23,000 * .88^n = 2,300

.88 ^ n = .1

n log .88 = log .1
n = log .1 / log .88 =

n = 18 years

is there a way to do this without using logarithms?

and thx btw.

Nope, except trial and error
