Merseyside Chemicals are considering replacing their existing machine with a new, more efficient one. The old machine was purchased 4 years ago for $60,000,000 and had an estimated useful life of 6 years; it can be sold today for $30,000,000. The new machine will cost $75,000,000 but will have a 10 year life and scrap value at the end of the 10 years of $10,000,000. The new machine will require shipping and installation costs of $8 million. As the new machine is more efficient it will also require an increase in net working capital of $15,000,000 today. Merseyside Chemicals depreciates all assets straight-line over their useful life and pays tax at the company rate of 30%. The initial investment at t=0 for the incremental decision of selling the old and buying the new machine is (to the nearest dollar): a. ($70,000,000) b. ($71,000,000) c. ($68,000,000) d. ($55,000,000) e. ($75,000,000)
