A new electronic process monitor costs $990,000. This cost could be depreciated at 30% per year (Class 10). The monitor would actually be worth $100,000 in five years, The new monitor would save $460,000 per year before taxes and operating costs Suppose the new monitor requires us to increase net working capital by $47,200 when we buy it. If we require a 15% return, what is the NPV of the purchase? Assume a tax rate of 40%. (Do not round intermodiate calculations. Found the final answer to 2 decimal places. Omit $ sign in your response.) NPY
