Problem $5$ Calculating project cash flows and NPV

A corporation is considering the purchase of new equipment. Although the machine being considered will result in an increase in earnings before interest and taxes of $25,000$ SAR per year, it has a purchase price of $108,000$ SAR, and it would cost an additional $3,000$ SAR to properly install the machine.

This machine has an expected life of $8$ years, after which it will have no salvage value. Also, assume that there is simplified straight$-$line deprecation and that this machine is being depreciated down to zero, a $33$ percent marginal tax rate, and a required rate of return of $12$ percent.

a$.$ What is the initial outlay assoicated with this project?

b$.$ What are the annual after$-$tax cash flows associated with this project for years $1$ through $9?$

c$.$ What is the terninal cash flow in year $10?$
