Notes Over 8.6 Exponential Decay C is initial amount t is the time period r is the growth rate You bought a used truck for $15,000. The value of the truck will decrease each year because of depreciation. The truck depreciates at the rate of 8% per year. 1. Use the exponential decay model in Example 1 to estimate the value of your truck in 5 years.
