Can you please help show me how to solve this capital budgeting problem:

Builtrite D is considering the purchase of a new machine for $500,000 which would require a $5000 installation charge.Employees would need to go through a brief training session to operate the machine properly which would cost $25,000. In addition, an increase in net working capital of $30,000 would be required.The machine has an expected life of 10 years and due to efficiencies, labor costs are expected to decrease $150,000 annually (before depreciation and taxes).Assume straight-line depreciation, a 34% marginal tax rate and a cost of capital of 15%.Should Builtrite D purchase the machine?
