1.) A machine costs $60 and requires $35 in maintenance for each year of its three year life. After three years, this machine will be replaced. If the machine belongs in a 30% CCA class and has no salvage value, what is the EAC? Assume a tax rate of 34% and a discount rate of 14%.

2.) The machinery required for a three year project costs $20,000, belongs in a 15% CCA class, and will require a net working capital investment of $5,000 up-front. The project generates after-tax operating income of $11,500. The fixed assets will be sold for $2,000 at the end of the project. If the firm has a tax rate of 34% and a required return of 10%, what is the project NPV?
