St. Johns River Shipyard's welding machine is 15 years old, fully depreciated, and has nosalvage value. However, even though it is old, it is still functional as originally designedand can be used for quite a while longer. A new welder will cost $182,500 and have anestimated life of 8 years with no salvage value. The new welder will be much moreefficient, however, and this enhanced efficiency will increase earnings before depreciationfrom $27,000 to $74,000 per year. The new machine will be depreciated over its 5-yearMACRS recovery period, so the applicable depreciation rates are 20.00%, 32.00%, 19.20%,11.52%, 11.52%, and 5.76%. The applicable corporate tax rate is 40%, and the project costof capital is 12%. Should the old welder be replaced by the new one
