Moose Pastures Inc. is considering a seven$-$year project to improve its production efficiency. Buying a new assembly machine for $$708,000$ is estimated to result in $$213,000$ in annual pre$-$tax cash flows. The machine has a CCA rate of $30\%$ per year, and it will have a salvage value of $$70,000$ at the end of the project. The machine also requires an initial investment in inventory of $$20,000($in year zero$),$ which will be recovered at the end of the project $($in year $7).$ If the tax rate is $40\%$ and the discount rate is $10\%,$ what is the NPV of the machine purchase? $($Assume the CCA pool remains open and that there are no capital gains$/$losses$.)$ Correct answer is $$132,337.$

$($My question$)$ Hi I am confused on how it got $132,337.$ I know there's a formula but can you walk me through the steps to get this correct answer?
