Wildhorse Company purchased a truck for $40,000. The company expected the truck to have a useful life of four years or 136,000 kilometres , with an estimated residual value of $6,000 at the end of that time. During the first and second years, the truck was driven 25,000 and 29,000 kilometres, respectively.
