Answer:
a. What is the Year 0 net cash flow?
-$820,000 - $17,500 - $15,500 = -$853,000
b. What are the net operating cash flows in Years 1, 2, 3?
Operating cash flow year 1 = {[$338,000 - ($837,500 x 1/3)] x (1 - 25%)} + ($837,500 x 1/3) = $323,292
Operating cash flow year 2 = {[$338,000 - ($837,500 x 0.4445)] x (1 - 25%)} + ($837,500 x 0.4445) = $346,567
Operating cash flow year 3 = {[$338,000 - ($837,500 x 0.1481)] x (1 - 25%)} + ($837,500 x 0.1481) = $284,508
c. What is the additional Year 3- cash flow (i.e. after tax salvage and the return of working capital)?
= $62,031 + [($604,000 - $62,031) x 0.75] + $17,500 = $486,008
d. If the project's cost of capital is 12%, should the machine be purchased?
using a financial calculator, NPV = $260,373, so the project should be accepted
