Gold Star Industries is contemplating a purchase of computers. The firm has narrowed its choices to the SAL 5000 and the HAL 1000. Gold Star would need nine SALs, and each SAL costs $3,100 and requires $360 of maintenance each year. At the end of the computers eight-year life, Gold Star expects to sell each one for $210. Alternatively, Gold Star could buy seven HALs. Each HAL costs $3,450 and requires $415 of maintenance every year. Each HAL lasts for six years and has a resale value of $200 at the end of its economic life. Gold Star will continue to purchase the model that it chooses today into perpetuity. Gold Star has tax rate of 34 percent. Assume that the maintenance costs occur at year-end. Depreciation is straight-line to zero. What is the EAC of each model if the appropriate discount rate is 9 percent?
