Question

A new car worth 25,000 is depreciating(loses value) in value by 1,250 per year. Determine how many years will it take for the car to be worth 8,500

Answer 1

The value x years from now will be
   v(x) = 25000 - 1250x

Filling in the given information, we have
   8500 = 25000 - 1250x
   8500 - 25000 = -1250x
   -16500/-1250 = x = 13.2

It will take 13.2 years for the car to be worth 8,500.
