A firm needs to obtain a specialized machine, which would cost $$630000$ to buy. It would be depreciated at the rate of $$63000$ per year for both accounting and tax purposes, and could be sold in five years for $$315000.$ The firm has the option of leasing the machine for five years. This would be an operating lease, with payments of $$88200$ per year at the beginning of each year. The company is subject to a fax rate of $40\%$ and its pre$-$tax borrowing cost is $7\%.$ What is the total undiscounted after$-$tax net cash flow associated with this proposed lease?

$-$$$652680$

$-$$$128520$

$-$$$75600$

$$239400$
