A firm needs to obtain a specialized machine, which would cost $$690000$ to buy. It would be depreciated at the rate of $$69000$ per year for both accounting and tax purposes, and could be sold in five years for $$345000.$ The firm has the option of leasing the machine for five years. This would be an operating lease, with payments of $$96600$ per year at the beginning of each year. The company is subject to a tax 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?

$-$$$714840$

$-$$$82800$

$-$$$140760$

$$262200$
