A machine costs $1,000 and has a 3 -year life. The estimated salvage value at the end of three years is $100. The project is expected to generate after tax-cash flows of $600 per year. If the required rate of return is 10%, what is the NPV of the project? (Do not round intermediate computations. Round final answer to the nearest whole number.) $492 $1,492 $567 $1,567
