If you lease it, the payments will be $7,500 per year, payable at the beginning of each year. If you buy the car, you can apply a CCA rate of 30% per year. The tax rate is 35%.

Assume that the car has projected salvage value of $700 and the asset pool is closed, what would be NAL. Should you buy or lease? Why?
