Foster uses the straight-line depreciation method. The following events took place in Year 2. March 1: Peripheral equipment costing $30,000 was added to the system. This equipment has a useful life of seven years and a residual value of $2,000. This equipment can be used with several different computers. Foster could potentially replace the computer system before the disposal of this peripheral equipment. September 1: Additional accessories were added to the computer system, costing $250,000.
