Purchase a more advanced machine for $255,000. This machine will require $18,000 per year in ongoing maintenance expenses and will lower bottling costs by $10,000 per year. Also, $36,000 will be spent up front to train the new operators of the machine. Suppose the appropriate discount rate is 7% per year and the machine is purchased today. Maintenance and bottling costs are paid at the end of each year, as is the cost of the rental machine. Assume also that the machines will be depreciated via the straight-line method over seven years and that they have a 10-year life with a negligible salvage value. The marginal corporate tax rate is 28%. The NPV of purchasing the advanced machine is?
