A tractor was purchased for $30,000 six years ago. what is the value of the tractor today if the depreciation rate was 2.5%?

Initial cost = $30,000

Depreciation rate = 2.5%

Depreciation expense per year = 30,000*2.5/100 = $750

In six years,

Depreciation = 6*750 = $4,500

Value of the tractor = Initial cost - Depreciation = $30,000 - $4,500 = $25,500
