18. A new truck costs $32,000. The car’s value will depreciate over time, which means it will lose value. For tax purposes, depreciation is usually calculated linearly. If the truck is worth $24,500 after three years, write an explicit formula for the value of the car after n years.

First we need to calculate the percent of change by dividing:\[\frac{ 32500 }{ 24500 }\]@Dallen41

1.32

So, 132% as we move the decimal two times to the right.

OpenStudy (kash_thesmartguy):

Divide 132 by 3 to get the percent of change for one year, so do:\[\frac{ 132 }{ 3 }\]

Ok. 44

Appreciate it

Now, we can create the formula: \[n=0.44*32500\]
