7. Xtronics Electronics Inc. needs to replace an old solder bath machine with a new, more efficient model. The old solder bath machine was purchased for $125,000 10 years ago and has been fully depreciated. The new solder bath machine costs $200,000. It will cost the company another $15,000 to get the new solder bath machine to the factory and get it modified for Xtronics production operations. The old solder bath machine will be sold for $25,000. The new solder bath machine is also being depreciated on a simplified straight-line basis over 10 years. The new solder bath machine will be operated for 10 years and then will be sold for $35,000. Sales are expected to increase by $45,000 per year while operating expenses are expected to decrease by $17,500 per year. Xtronics' marginal tax rate is 35%.
