A new car was valued at $28,000, and it's value depreciated to $14,000 over the next 3 years. Use the exponential equation for d
kompoz [17]
The exponential equation (in thousands) is:
V = 28 e^{-rt}
plug in t=3 yrs, and solve for 'r'.
14 = 28 e^{-3r} \\  \\ \frac{1}{2} = e^{-3r}  \\  \\ ln(\frac{1}{2}) = -3r \\  \\ r = \frac{ln(\frac{1}{2})}{-3} = 0.231 = 23.1%

Find value of car when t = 10
V = 28e^{-2.31} = 2.779
