Santa$$s Helpers Inc. is considering a six$-$year project to improve its toy production efficiency. Buying a new toy$-$soldier assembly machine for $$500,000$ is estimated to result in $$135,000$ in annual pre$-$tax cost savings. The machine has a CCA rate of $30\%$ per year, and it will have a salvage value of $$50,000$ at the end of the project. The machine also requires an initial investment in inventory of $$20,000,$ which will be recovered at the end of the project. If the tax rate is $40\%$ and the discount rate is $10\%,$ what is the NPV of the machine purchase?
