A company is considering buying either Machine A or Machine B. Machine Both machines cost $44,451, but Machine A is expected to last 4 years and generate cash flows of $16,956 each year, while Machine B is only expected to last 2 years, but generate cash flows of $34,142 each year. If the WACC is 10%, which machine is the best investment? Calculate the RELEVANT NPV of each investment project, then obtain the difference. That is, enter the NPV of buying Machine A - the NPV of buying Machine B. Hint: remember that the NPVs of projects of different lengths are not directly comparable... Round to the nearest dollar (no decimals)
