The Wildcat Oil Company is trying to decide whether to lease or buy a new computer$-$assisted drilling system for its oil exploration business. Management has decided that it must use the system to stay competitive; it will provide $$3\mathrm{.}3$ million in annual pretax cost savings. The system costs $$10$ million and will be depreciated straight$-$line to zero over its five$-$year life, after which it will be worthless. Wildcat's tax rate is $25$ percent and the firm can borrow at $9$ percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $$2,180,000$ per year. Lambert's policy is to require its lessees to make payments at the start of the year.
