Jeff & Bezos is a fresh groceries delivery company. The company has access to borrowing funds at a pre$-$tax rate of $6$ percent per year. Jeff & Bezos pays income taxes using $21\%$ tax rate. The company would like to start using high$-$speed low$-$altitude drones to deliver grocery purchases directly to residential customers' backyards. The required fleet of drones costs $$6,000,000.$ If the company chooses to buy them, the drones would be losing their economic value following the straight$-$line depreciation method during a six year period. The fleet of drones, due to their heavy usage, would have no salvage value in six years. Instead of buying the fleet of the drones, Jeff & Bezos is also contemplating leasing them for an estimated pre$-$tax annual cost of $$1,200,000$ for six years from a different company, Nets & Flicks, that owns the required number of drones. Nets & Flicks is in the same tax bracket as Jeff & Bezos.
