Your company wants to purchase a new network file server for its wide-area computer network. The server costs $24,000. It will be obsolete in three years. Your options are to borrow the money at 10% or lease the machine. If you lease it, the payments will be $9,000 per year, payable at the beginning of each year. If you buy the server, you can apply a CCA rate of 30% per year. The tax rate is 40%. Suppose the server had a projected salvage value of $1,000.

Assuming the asset pool remains open, calculate the NAL. (Do not round intermediate calculations. Round the final answer to 2 decimal places. Omit "$" sign in your response.)
